The Iguanas’ facility with Tex-Mex, horn-honkin’ ’50s-style R&B, and salsa has garnered this New Orleans quintet a well-deserved reputation as a great dance band. With D.C.-raised Derek Huston on saxophone, and a tight rhythm section led by ex-Tav Falco & the Panther Burns bassist Rene Coman, this always-on-tour bunch has kept people moving on the floor since the early ’90s. But what have often been overlooked are the yearning pop melodies of vocalists Joe Cabral and Rod Hodges. Inspired by Ritchie Valens, Buddy Holly, and current New Orleans resident Alex Chilton, these two deliver their well-crafted strains so they stick in your head in addition to shaking your hips. At 9:30 p.m. at Twist & Shout, 4800 Auburn Ave., Bethesda. $15. (301) 652-3383. (Steve Kiviat)
