Feb. 2 Euforquestra w/ The LymphNodes Maniacs Waiting Room Lounge, 6212 Maple St. 9 p.m., $8, onepercentproductions.com If you love something, you must give it away for free. Somebody said that. Sting? I dunno. Anyway, that’s what Euforquestra did with its album Soup . (Ativan) Wanting to build a fan base for their afro-beat/funk infused sound, the group chose to let fans new and old have their new album for free on their site. The Iowa City/Fort Collins-rooted group is hoping to bring converts out to their show, a fusion of a bunch of world genres that amount to ‘dancing your ass off.’
