As a songwriter and guitarist, Richard Thompson’s career is unparalleled. His albums with Fairport Convention and his then-wife Linda Thompson are folk-rock classics, and his distinctive guitar work has appeared on LPs by Nick Drake, John Martyn, Bonnie Raitt and BeauSoleil. In the last decade, Thompson has been in workman mode, steadily cranking out understated but compelling records. Still—recorded with Jeff Tweedy at the Wilco Loft in Chicago—maintains the meticulous standard set by 2013’s fantastic Buddy Miller-produced effort, Electric. “Beatnik Walking” is a mostly acoustic showcase, with Thompson’s Celtic melodies dancing over a simple folk thump; “Where’s Your Heart” sounds like it could fit in on his classic Shoot Out the Lights; and seven minute-plus “Guitar Heroes” is a playful homage to his heroes, including Chuck Berry, Django Reinhardt and Les Paul. In the producer role, Tweedy maintains the same reverent approach he’s brought to recent albums by Mavis Staples and the late Pops Staples. It’s tempting to imagine a scenario in which Tweedy pushed harder for more of the experimental approach that he’s embraced with Wilco, or added some of the dismantled-pop touches of his side project Tweedy, but here, he allows Thompson to be Thompson, and as is always the case with the guitarist, it’s worth hearing.
