Free; 6 p.m.
WFPK has arranged a great lineup of soulful artists for your listening pleasure next Wednesday. First up at 6 p.m. is Vessel, a folksy group of highly sought-after solo musicians who have banded together to integrate their best ideas into a lively, danceable performance. Next is Joseph Arthur, the shining star of the event, who will begin his show at 7:30 p.m. The Akron, Ohio-born, Brooklyn-dwelling singer/songwriter creates textured and rich sonic layers, mixing them while onstage with a complicated array of switches and foot pedals — truly a sight to behold. The night will take a turn at 9 p.m. with a roots-rock twist on traditional Celtic music played by Kansas City band The Elders. As always, B.Y.O.B. is prohibited. —Simon Isham
