10 p.m. Saturday
House of Blues, 225 Decatur St., 310-4999; www.hob.com
Yeasayer set an impossibly exotic pop standard with "2080," the world-beating, choir-chanted first single from 2007 debut All Hour Cymbals (We Are Free). The Brooklyn band went weirder on February follow-up Odd Blood (Secretly Canadian), obfuscating could-be hits with ghost-in-the-machine vocals and ping-ponging electronics. Washed Out opens. Tickets $18.50.
