Rachelle Ferrell

The Live collection does, however, offer a few surprises. It’s intriguing, for instance, to compare Ferrell’s lovely ’89 interpretation of Cy Coleman’s under-appreciated “With Every Breath I Take” with her decidedly more assured live version from ’97 (boosted by some masterful keyboard work by surprise guest George Duke). Two other ’97 crowd-pleasers-gorgeous renditions of Charles Aznavour’s “Me Voila Seul” and “On Se Reveillera”-are equally wonderful additions to the eclectic Ferrell oeuvre.

Released a year after his successful duets double album, French icon Charles Aznavour's 2009 follow-up is another collaborative effort, this time with Los Angeles-based Clayton-Hamilton Jazz Orchestra. Featuring duets with jazz vocalists Rachelle Ferrell and Dianne Reeves, it includes 14 big-band interpretations of both his classic standards ("La Boheme," "Comme Ils Disent"), and several less familiar tracks ("Je N'ouiblerai Jamais," "Des Amis Des Deux Cotes").

Grouped together, as they are on the double-disc From Q with Love, producer/arranger/conductor Quincy Jones' love songs sound an awful lot alike. The high-gloss production, the silky smooth harmonies, the lead singers – who all happen to bear a strong vocal resemblance to Jones' most famous client, Michael Jackson – and even the tunes themselves have a one-note, suite-like sweep to them that can be mind-numbingly tedious after a couple hours. It helps that From Q with Love is loaded with hits from Jones' past 30-plus years (Patti Austin and James Ingram's "Baby, Come to Me" and "How Do You Keep the Music Playing?," Ingram's "One Hundred Ways" and "Just Once," Jackson's "Human Nature," and a handful of tracks from Jones' 1989 golden showpiece Back on the Block.

DreamWeaver marks George Duke's return to recording after a three-year silence, and his first since the death of his wife Corine in 2012. While he is always diverse, this set is uncommonly so. The opener, a slippery, atmospheric title intro, flows directly into the Latin-tinged "Stones of Orion," a jazz tune with Duke on piano, Rhodes, and synths, Stanley Clarke on upright bass, and a four-piece horn section. It's shimmering groove-oriented jazz that reflects the time that Duke spent with Cannonball Adderley. "Trippin'" is a funky, jazzed-up R&B tune where he offers his autobiography; it features some fine muted trumpet work by Michael Patches Stewart. "Missing You" is a jazz ballad tribute to Corine, with the finest vocal Duke has laid down in a decade. But there's funk here, too, in the fat stomper "Ashtray."

Rhino repackaged and re-released five George Duke LPs on Warner Bros. – Snapshot, Illusions, Is Love Enough?, After Hours, and Cool – as a slipcased box set. It's not a bad way to acquire the albums if you don't already own them, but isn't recommended for the casual fan.
