Thanks to You Boz Scaggs

He didn't go so far as to call it Silk Degrees II, but Dig is as close as Boz Scaggs is likely to come to recording the sequel to his most commercially successful and, for many, best-loved record (unless you count 1977's underrated follow-up, Down Two Then Left). Reunited after all these years with Silk Degrees collaborator David Paich, Scaggs makes a successful return to the blue-eyed soul of his late-'70s works on tracks such as "Desire" and "Thanks to You," the latter featuring tastefully muted trumpet work from Roy Hargrove.

Boz Scaggs has had a long and varied career, playing blues, singing soul music, recording hits with smooth grooves, and taking his time with his temperamental muse. The Essential Boz Scaggs features 32 songs that tell the story of his solo career. It starts, after his stint in the Steve Miller Band, with his Atlantic Records self-titled debut album. Duane Allman fires up “Loan Me a Dime” with his trademark guitar work. Scaggs moved to Columbia Records, where he released a number of fine albums, culminating with the sleek, sophisticated grooves of Silk Degrees, provided by the band that would become Toto. Six tracks appear here, including the hits “Lowdown,” “Lido Shuffle,” and “Harbor Lights.”

But Beautiful is an album of pop standards by Boz Scaggs, released in 2003. An assured, logical next step in an enduring musical career, But Beautiful signals the arrival of an important new voice in the domain of the great American songbook. It features Scaggs performing standards such as Sophisticated Lady, and Bewitched, Bothered and Bewildered with the classic jazz quartet that includes pianist and arranger Paul Nagel and bright new star from the San Francisco jazz scene, saxophonist Eric Crystal. But Beautiful reached number one on the Billboard Top Jazz Albums chart in 2004.

After the burnished, mellow Moments, Boz Scaggs put some grit back into his music with this third album, Boz Scaggs & Band. Not that he got down and dirty – his blue-eyed soul and funk is still sleek and stylish, music for uptown parties, not downtown juke joints. But Scaggs gave his band equal billing on the title here because they carry equal weight on Boz Scaggs & Band. It's a true band album, showcasing the group's tight interplay as much as it does Scaggs' vocals. Sometimes, the band almost dominates the proceedings too much, as they do on "Runnin' Blue," where they're as splashy as a Vegas big band. Such excesses are balanced by the nimble "Up to You," this album's irresistible foray into country – something that was a regular Boz feature at this point – and the brief, breezy "Here to Stay," which helps keep things light and casual. But the best thing about Boz & Band is hearing that band play, particularly on "Flames of Love" and "Why Why," where they get down low, playing funky rock and soul that holds its own with Little Feat's Meters-inspired grooves.

Boz Scaggs considers Out of the Blues to be the final installment in a (primarily covers) trilogy that began with 2013's Memphis and continued with 2015's A Fool to Care, excellent outings that reflected Scaggs' desire to reach back into the cradle of inspiration. This set looks back to his 1965 debut album Boz (a solo acoustic covers set released only in Sweden by Polydor) and 1997's criminally overlooked Come on Home, a woolly, house-rocking collection of (mostly) vintage R&B and soul-blues covers, for its foundation. While these early recordings don't necessarily sound similar, they make use of the work of a particular set of performers and songwriters – including Jimmy Reed and Don Robey (credited with many of Bobby "Blue" Bland's hits) – who have always provided inspiration and grounding throughout his lifetime. Whereas Scaggs' two previous offerings were produced by Steve Jordan, Boz opted to co-produce Out of the Blues with Chris Tabarez and Michael Rodriguez, creating an impression of intimacy and loose immediacy that ranks with the swampier feel of Come on Home. His band here includes holdovers bassist Willie Weeks, Jim Cox, and rhythm guitarist Ray Parker, Jr. as well drummer Jim Keltner (the kitman on Come on Home), and guitarists Doyle Bramhall II and Charlie Sexton; there is also a selectively and impactfully used three-piece horn section.

On Memphis, Boz Scaggs pays tribute to the city's magnificent soul tradition, Al Green, and producer Willie Mitchell and his Royal Recordings studio, whose location and personnel were used to cut it in three days. Produced by drummer Steve Jordan, the core band includes the singer and Ray Parker, Jr. on guitars, and bassist Willie Weeks, augmented by the Royal Horns & Strings, a small backing chorus, sidemen, and guests. Green's influence is celebrated in the opener, Scaggs' "Gone Baby Gone." Its wafting B-3, Rhodes, fluid electric guitars, and a tight backbeat underscore his baritone croon to excellent effect. If there were doubts about the quality of his voice at this juncture, they're immediately dispelled when his sweet falsetto emerges. In his cover of Green's "So Good to Be Here," Scaggs references him but digs deeper into his own trick bag with more rounded, earthier highlights.
