January 28 The Show is the Rainbow w/ Machete Archive and Prairies Waiting Room, 6212 Maple St. 9 p.m., $8, onepercentproductions.com Love or loathe, there’s one thing you can’t do with The Show is the Rainbow: ignore. Darren Keen’s histrionic antics combine angst and rock front man wriggling. He’s stripped back down to the one-man-band format, singing and wailing his screeds over pre-recorded electronic music. It’s a format certainly unique in the Lincoln/Omaha area. Also on hand are post-rockers Machete Archive, an up and coming prog band, and Prairies, noisy garage punks with wonderfully lo-fi organ sounds thrown in.
