Milton "Bags" Jackson (January 1, 1923 – October 9, 1999) was an American jazz vibraphonist, usually thought of as a bebop player, although he performed in several jazz idioms. He is especially remembered for his cool swinging solos as a member of the Modern Jazz Quartet and his penchant for collaborating with hard bop and post-bop players…

In some ways, this is a strategic retreat for Antonio Carlos Jobim after the classical departures of the '70s – a retrospective of past triumphs, including some of the most trod-upon standards ("Ipanema," "Desafinado," "One-Note Samba," etc.), with Claus Ogerman again at hand. But these are thoughtful retoolings, some subtle, some radical, ranging in backing from a lonely piano to elaborate yet sensitive Ogerman orchestral flights that cram more complexity than ever into the spaces (listen to his beguilingly involved take on "Double Rainbow") with only a few overbearing faux pas. Jobim's own vocals sound increasingly casual in temperament as he serves them up in an unpredictable mixture of Portuguese, English and scat. And there is much unfamiliar material here, often dressed up in a brooding classical manner.

Joni Mitchell reached her commercial high point with Court and Spark, a remarkably deft fusion of folk, pop, and jazz which stands as her best-selling work to date. While as unified and insightful as Blue, the album – a concept record exploring the roles of honesty and trust in relationships, romantic and otherwise – moves away from confessional songwriting into evocative character studies: the hit "Free Man in Paris," written about David Geffen, is a not-so-subtle dig at the machinations of the music industry, while "Raised on Robbery" offers an acutely funny look at the predatory environment of the singles bar scene. Much of Court and Spark is devoted to wary love songs: both the title cut and "Help Me," the record's most successful single, carefully measure the risks of romance, while "People's Parties" and "The Same Situation" are fraught with worry and self-doubt (standing in direct opposition to the music, which is smart, smooth, and assured from the first note to the last).

Clarence "Gatemouth" Brown's tough-minded approach to the blues, country, Cajun, and jazz insures a minimum of nonsense and a maximum of variety, while his virtuosity on the guitar and fiddle insures the highest standards. Nonetheless, Brown's 1997 album is a landmark for the 73-year-old picker who won a Rhythm & Blues Foundation Pioneer Award. All 13 tunes on Gate Swings find Brown working with his regular road quartet plus a 13-piece horn section, enabling him to prove that Duke Ellington, Count Basie, and Lionel Hampton have been as important to his music as any bluesman or Creole fiddler. Gate Swings includes tunes by all three of those big-band leaders as well as compositions by Buddy Johnson, Percy Mayfield, Louis Jordan, and Brown himself, and they all swing with the massive force that only a big horn section can muster. Brown has leaned in this direction before, but Gate Swings is special, because it features the horn arrangements of Wardell Quezergue, an alumnus of the Dave Bartholomew band who arranged many of the best New Orleans R&B hits in the '60s and '70s.

You know it's about time somebody took all the little records that Big Joe Turner managed to make back in the day and brought them out in sequence the way they appear in the Classics Chronological Series. Nobody in the world ever sounded quite like Joe Turner and nobody ever will. There is a magical quality that makes his blues performances feel like rituals full of clarity and grace. Each and every Joe Turner record is as beautiful as a massive stand of tiger lilies growing up through the middle of a brickyard, silent, solid, and dignified under the dew in the first light of dawn. Incredibly, despite his enormous popularity during the Second World War, by 1949 this gifted vocalist was scuffling to get recording gigs. Ten tasty sides were cut in Los Angeles for the MGM label with a solid band fairly bursting with hot horns and driven by Pete Johnson's piano. Joe Turner closed out the year by waxing two sides for Rouge Records in Baton Rouge, LA, and four for the Freedom label in Houston, TX. In April of 1950, Joe Turner made a fistful of records in New Orleans backed by Dave Bartholomew & His Orchestra with Fats Domino at the piano.

Almost three centuries ago, in 1723, Johann Sebastian Bach (1685–1750) finished writing his Two-Part Inventions, BWV 772–786. Designed for the education of his son Wilhelm Friedemann, these fifteen works explore contrapuntal writing and a variety of different dance styles. Then as now, musicians learned their trade by mastering performance technique and the idiomatic characteristics of their instrument. On this album, pianist Moisés P. Sánchez reinvents this extraordinary set of pieces by employing Bachian principles: reworking on well-known works to translate them into a modern idiom, while retaining their essence. Commissioned by the Fundación Juan March, this project harks back to the original spirit of Bach’s Inventions, taking a creative idea and reimagining it in order to stimulate the musical imagination and seduce the listener with new sonorities.

Bossa nova is not unfamiliar to Diana Krall, but 2009's Quiet Nights is her first record devoted to the gently swaying rhythm. Teaming up again with arranger Claus Ogerman, who last worked with Krall on 2001's The Look of Love and who also frequently collaborated with bossa nova godfather Antonio Carlos Jobim, Krall winds up with a mellow, lazy album that recalls the relaxed late-night sophistication of Jobim's duet album with Frank Sinatra, which Ogerman also happened to arrange and conduct. It's not just the sound, it's the songs: how '60s standards like Bacharach/David's "Walk on By" sit next to three Jobim tunes, a song by Marcos Valle ("So Nice"), and a few American Songbook standards placed at the beginning, the better to ease listeners into purer bossa nova at the end.

Way back in 1963, Paul McCartney sang "A Taste of Honey" on the Beatles' debut album, and "Til There Was You" on their second LP, establishing that his tastes ran far beyond the world of rock & roll and R&B. Over the years, he touched upon pre-rock & roll pop – writing pastiches like "Honey Pie" with the Beatles and, crucially, snatching up the publishing rights to many of these tunes, thereby building his MPL empire – but he never devoted a full record to the style until 2012's Kisses on the Bottom, a cheekily titled (pun not only intentional but solicited) collection of songs you know by heart…
