As disco became an important part of the international music business, European producers began working in exotic flavors into the disco beat to create unique and competitive recordings. A good example of this trend is Santa Esmeralda, a Spanish-themed studio group that wove elements of flamenco, salsa, and other Latin musical styles into its Euro-disco sound. Although the group's sound was about as genuinely Spanish as Herb Alpert & the Tijuana Brass (Santa Esmeralda was the brainchild of French record producers), the result was a crossover success that spawned several club-favorite albums and a notable pop hit in the band's Latinized cover of "Don't Let Me Be Misunderstood".

Following up the superb Elegant Gypsy was no mean feat, but Al di Meola gave it his best shot with the similarly styled Casino, released in 1978. Featuring a core band of Steve Gadd, Anthony Jackson, and Barry Miles (whom di Meola came up with before the guitarist was invited to join Return to Forever), the playing is sharp and fiery, matching the youthful intensity of the leader. Di Meola is a good composer in the fusion idiom, and the four original compositions on Casino, although clearly bearing the mark of Chick Corea's influence, are strong. His "Fantasia Suite for Two Guitars," featuring di Meola accompanying himself via multi-tracking, is beautiful and dramatic, and hints at the guitarist's later all-acoustic works such as Friday Night in San Francisco.

Doug Sahm once sang, "You just can't live in Texas if you don't have a lot of soul," and, as a proud son of the Lone Star state, he seemed bent on proving that every time he stepped in front of a microphone. Whether he was playing roots rock, garage punk, blues, country, norteño, or (as was often the case) something that mixed up several of the above-mentioned ingredients, Doug Sahm always sounded like Doug Sahm – a little wild, a little loose, but always good company, and a guy with a whole lot of soul who knew a lot of musicians upon whom the same praise could be bestowed. Pulling together a single disc compilation that would make sense of the length and breadth of the artist's recording career (which spanned five decades) would be just about impossible (the licensing hassles involved with the many labels involved would probably scotch such a project anyway), but this disc, which boasts 22 songs recorded over the course of eight years, is a pretty good starter for anyone wanting to get to know Sahm's music.

It should come as no surprise that Enrique Iglesias' 2008 Greatest Hits begins in 1999, when he made the leap from the Latin market into the mainstream. All his very successful '90s albums on Fonovisa are bypassed, written off as prehistory, so the spotlight shines only on his English-language singles of the new millennium: the club tracks and syrupy slow songs that gave him a significant number of crossover hits. With the exception of a couple of minor blips on the charts like 2000's "Sad Eyes," all these are here, starting with 1999's "Bailamos" and "The Rhythm Divine," running through 2000's "Be with You" and 2001's "Hero," stopping for 2004's "Not in Love," winding up with 2007's "Do You Know? (The Ping Pong Song)" and wrapping up with two new duets, "Away" with Sean Garrett and "Takin' Back My Love" with Ciara. While this approach may lop off half of his career, it also does exactly what hits collections should do: it gives the casual listener the hits they want to hear and nothing else.

Expresso 2222, Gilberto Gil's first album back in Brazil after spending two years in exile, is a spirited return to form, filled with driving, funky bass, hammering piano, and percussive guitar work. Gil's compositions are on par with the best of his 1968 and 1969 self-titled albums, but is a more even overall affair forsaking the outright diversity Gil showed on those previous albums for a more cohesive set of songs, and while the performances aren't as outrageously groundbreaking, with Expresso 2222 Gil had already proved how far he was capable of pushing the envelope, and so the insane arrangements were no longer necessary. This makes Expresso 2222 one of Gil's most immediately palatable releases of his entire career, and compared to the standards of global rock & roll it is of the most compelling and complex yet accessible albums released in the 20th century. Gil's compositions are melodic and beautiful, and his arrangements are imaginative as always; from using a chorus of backing vocals to great effect on "O Canto de Ema" and "Sai do Sereno" to the rhythmic interplay between Gil's guitar, vocals, and layered percussion on the title track, Gil is in top form throughout the album.

America/Brasil is a rollicking, celebratory album that keeps Herbie Mann on the winning streak he started with the release of Peace Pieces in 1995. Recorded during a week of concerts to mark his 65th birthday in April 1995, this disc is much stronger than its immediate predecessor, Celebration, also taken from the same week of live concert performances at New York's Blue Note jazz club. The material here is superb, and the playing top-notch. As the title implies, the emphasis here is on Mann's Brazilian side, but there are touches of the non-Brazilian with Bill Evans' "Peri's Scope" and Miles Davis' "All Blues." "Summertime" is recast in an Afro-Cuban mode with Paquito D'Rivera sharing the solo space on alto sax. However, lengthy Brazilian showstoppers are placed at the beginning, middle, and end of this wonderful disc. The opening "Keep the Spirits Singing" is propelled by the polyrhythmic pulse of percussionists Cyro Baptista and "Café," and the 17-minute title track finale features trumpeters Randy Brecker and Claudio Roditi, trombonist Jim Pugh, and guitarist Romero Lubambo.

Marcos Valle was the Renaissance man of Brazilian pop, a singer/songwriter/producer who straddled the country's music world from the early days of the bossa nova craze well into the fusion-soaked sound of '80s MPB. Though his reputation in America never quite compared to contemporaries like Caetano Veloso, Milton Nascimento, Gilberto Gil, or even Tom Ze, Valle is one of the most important and popular performers in the history of Brazilian pop.

The Gipsy Kings are largely responsible for bringing the joyful sounds of progressive pop-oriented flamenco to the world. The band started out in Arles, a village in southern France, during the '70s when brothers Nicolas and Andre Reyes, the sons of renowned flamenco artist Jose Reyes, teamed up with their cousins. Their eponymous 1988 album sold tremendously in France and appeared on the Top Ten album charts in 12 European countries, including England; in 1989, it spent 40 weeks on the U.S. charts and went gold, becoming one of the few Spanish albums to do so.

At the height of her decade-long rise to fame, Julieta Venegas released her first live album, MTV Unplugged, a star-studded and meticulously arranged performance recorded before 450 adoring fans in Mexico City. She performs her greatest hits, of course, but she also adds to her set list relatively obscure songs – most delightfully "Esta Vez," a ballad from her debut album, Aquí (1998) – and several new songs, including the international chart-topping lead single, "El Presente." As with many MTV Unplugged albums, guest stars are featured throughout; most noteworthy among them here are Spanish rapper Mala Rodríguez, who performs in the place of Chilean rapper Anita Tijoux on "Eres Para Mí," and Brazilian superstar Marisa Monte, who duets in Portuguese on "Ilusión" (a new song written by Venegas, Monte, and Arnaldo Antunes). Guest star or not, the performances are each interesting in their arrangements, which are generally quite different from their studio original counterparts.
