Best ubiquitous opening act (2008)

RATATAT

Currently out on a cross-country headlining jaunt in support of two new albums—an eponymous debut and a collection of hip-hop remixes—the synthetically innocuous RATATAT seem completely out of their element. However, over the past year, the pulchritudinous pair of bedroom arena-rock instrumentalists (their titular onomatopoeia is misleading; think slow burn, not rapid fire) provided the ideal aural/visual background for drinking and schmoozing before Tortoise, !!!, or Mouse on Mars took the stage.
