On its newest release, Valtari, this Icelandic trio furthers its signature, enigmatic style with singer—and composer of the score to 2011 film We Bought a Zoo—Jónsi’s ethereal, falsetto-like vocals cascading over a swell of ambient instrumentation as luscious and grand as the group’s homeland. And if the live show’s opulent orchestration isn’t enough, North American tour attendees receive a free digital copy of a three-track EP with their ticket. Sat 8 p.m.
