Guitarist Ryley Walker may be only 24, but he channels the spirit of folksmen decades older. His home label, Tompkins Square, likely adds to this effect—the imprint reissues long-forgotten American roots music, along with contemporary artists who sound equally dust-covered—but on his own, Walker stands out as a singular player, with a voice reminiscent of Mark Kozelek’s and a style like Tim Buckley’s. This is his first Seattle show—don’t miss it. With Jason Scott Dodson, Whitney Lyman. Barboza, 925 E. Pike St., 709-9442, thebarboza.com. 8 p.m. $10. GE
