The 2006 release of The Essential Gloria Estefan satisfied a long unmet need for a career-spanning English-language retrospective, one that includes the singer's popular hits with Miami Sound Machine in the mid-'80s as well as her subsequent solo recordings. For years, Estefan fans had few best-of choices to choose from – the Spanish-language Exitos de Gloria Estefan (1990), the two-volume Greatest Hits series (1992, 2001), and the latter-day Amor y Suerte: Exitos Romanticos collection (2004) – with no alternatives, not even budget-line knockoffs. The long-overdue release of The Essential Gloria Estefan thankfully resolved this gripe, for it includes the highlights from all aspects of Estefan's varied output, spread generously across two jam-packed discs.

This record was originally released in 1991 after Taj had taken a break for a number of side projects including children's records. He was obviously refreshed - the record is full of new ideas and incorporates new production techniques, check out the lovely song "Every wind in the river" and also the scratching and rap stylings of "Squat that rabbit". A bit radical for blues but both work very well. Taj revists the song "Giant step" and also takes the traditional blues "Blues with a feeling" to New Orleans, with an added dash of steel guitar (!?!). Guests include banjo player David Johnson, guitarist David Lindley, Andy Kravitz and Bill Summers and the backing band sound great throughout. This is a really good, imaginative record that saw Taj coming back to form and his next couple of records in the 90s were even better.

It was much to soul singer Spanky Wilson's surprise – she didn't realize she had had such an impact – when British multi-instrumentalist/producer Will Holland contacted her in her Los Angeles home in 2004, professing his love of her music and wondering if she'd collaborate with him. Still, she agreed to go the studio, and together they did two songs, "Don't Joke with a Hungry Man" and "When You're Through," for Holland's solo project, Quantic, on the album Mishaps Happening. That collaboration worked out so well that they decided to make an entire record together, this time with Holland's full band, the Quantic Soul Orchestra. Wilson's lovely voice is the centerpiece of I'm Thankful, and it does show a bit of its age, but only in the best of ways, deepening it and giving it an added measure of credibility and authenticity while still preserving its expressiveness and strength.

Possibilities is a Herbie Hancock adventure record. This ten-cut smorgasbord features the ever restless pianist, composer, and arranger in the company of literally dozens of artists, from pop singers like Christina Aguilera, Sting, and Annie Lennox to rock legends such as Santana and Paul Simon to relative newcomers like John Mayer, Jonny Lang, and Joss Stone, as well as some renowned international performers, such as Angélique Kidjo and Raul Midón in a wide range of songs, styles, and moods. Hancock cut the record in studios all over the world, all the collaborations were done face to face, not long distance. Session musicians here include everyone from Stevie Wonder (who plays the harmonica solo on the cover of his tune "I Just Called to Say I Love You"), to Santana to Cyro Baptista, Willie Weeks, John Pattitucci, Steven Jordan, and Gina Gershon (the actress)! The standout cuts are the sensual read of Leon Russell's "A Song for You," sung by Aguilera, Simon's jazzed-up revisioning of his "I Do It for Your Love," and Lennox's read of "Hush, Hush, Hush," written by Paula Cole (whatever happened to her?).

Kenny Neal is such a terrific singer that he can make any kind of blues sound good. On Hoodoo Moon, Neal does the Delta blues justice on a version of Elmore James's "It Hurts Me Too," and does a fine job on the Chicago blues with "I'm a Blues Man." He even pulls off some James Brown funk on "Just One Step." Nonetheless, Neal makes his most valuable contributions when he allows his Louisiana roots to show. On "Don't Fix Our Love," for example, Neal lays his blues-harmonica solo and gravelly vocal over a New Orleans second-line parade rhythm. Lucky Peterson plays the Professor Longhair-like piano part expertly and does the same with the Fats Domino-like piano triplets on "Why Should I Stay." "The Real Thing" and the album's title track boast the slippery shuffle beat of upstate Louisiana's swamp blues.

Original Album Classics contains five albums by Cypress Hill: Cypress Hill (1991), Black Sunday (1993), Cypress Hill III: Temples of Boom (1995), Cypress Hill IV (1998), and Stoned Raiders (2001). That's the group's first four albums, plus its sixth – 2000's Skull & Bones was presumably left out because it's a two-disc album. For most casual fans, 2005's Greatest Hits from the Bong will be adequate, but this is a rather affordable way to obtain a major chunk of the group's catalog. The discs are presented as they were originally released, within standard jewel cases that slide inside a basic cardboard sleeve.

Like Lucien's first effort (1970's I Am Now), Rashida didn't set the world on fire commercially speaking, but it solidified Lucien's status as a purveyor of intelligent romantic ballads and poetic if not gushy lyrics. Even to fans of jazz/R&B/pop, Lucien is a love or hate proposition, and Rashida was the effort that all but etched his persona in stone. Produced by Shep Meyers and Larry Rosen, Rashida, displays Lucien's soothing baritone and romantic nature with much aplomb. As the arranger here, he also shows an immense capacity for melodies. Although this album has a few clunky but danceable tracks, at this point Lucien was much better at handling the ballads. "Kuenda," a mellow, wordless vocal, sets the stage for the album's ambience; "Would You Believe in Me" benefits from Lucien's relentless poesy and a strong idiosyncratic horn arrangement. To a listener, Lucien no doubt might seem like an odd bird, (having a track called "Satan" doesn't help), but often when the arrangements and Lucien's vocals are in sync, he is simply one of the most focused and emotional balladeers to even step in front of a microphone.

This disc, which has Dr. John at the controls as a producer, brings together a mix that brings out the best for all those concerned and involved with this project. There is no weakness here, it is a straight-ahead use of all the strengths of Shemekia Copeland, daughter of Johnny Copeland. The songs were well selected to effectively show off all her potency as a vocalist. There are some many good writers that are also players on this disc that the tunes fit like gloves. There are strong contributions by John "Fingers" Hahn, Mac Rebennack, and Shemekia Copeland herself. The tunes, varied in style, are all based in the deep blues, and were selected for their capability to push her vocal talents to constant new personal pinnacles. She keeps it interesting by varying the pace and on "The Push I Need," she sounds right at home singing this funky tune as a duet with Dr. John. She stays with the good Dr. through the tune as if she were doing this everyday. Then she turns around and seems just as comfortable singing "Happy Valentine's Day," as a slow bluesy torch-burner, with minimal accompaniment.

Wisely, Shout! Factory has picked up Maria Muldaur's two early-'90s recordings – this one and Louisiana Love Call – from the defunct Black Top label for reissue. While both these recordings are excellent, it's Meet Me at Midnite that offers a portrait of the artist as a hardcore R&B singer of the highest order. Produced by John Porter, Muldaur surrounds herself with crack studio players including Rick Vito, Johnny Lee Schell, Hutch Hutchinson, Bill Payne, and a slew of others. Where Louisiana Love Call focused on the music of New Orleans, Meet Me at Midnite digs deep into various dimensions of the Memphis sound – soul, R&B, and blues – and concentrates on the myriad stages and phases of love. While it's true that the set opens with "Trouble With My Lover" by the Crescent City's Allen Toussaint, its vibe is pure Memphis: funky, dirty grooves, packed in a tight cut-time beat and Muldaur shouting the blues with a big, clear ringing voice that wrenches emotion from every syllable. Likewise, the title cut by Vito and John Herron crawls down into the blues alley with killer slide guitar riffs winding their way around Muldaur's seductive vocals.

Recorded in Bruce Walford's studio in San Anselmo, this album sees the Sons in transition. Tim Cain, the sax player who co-founded the band with Bill Champlin back in 1965, had left, as had trumpet player Jim Beem. The stripped down band has an opportunity to stretch out on a number of fine Bill Champlin compositions, and the album also features the recorded debut of Terry Haggerty's "Follow Your Heart", a tune that would stay in the band's set list until Haggerty's departure in 2001 (a more polished version of the tune appeared on the out of print Circle of Love album, and there is a great performance on The Sons Live CD released in 1997). Soon after the release of this album Bill Champlin took the first of his sabaticals from the group, returning to a new rhythm section and a revised name (Yogi Phlegm) several months later. Not quite as good as Welcome to the Dance, this album still cooks pretty hard and is definitely worth a listen.
