The sprawling, eight-piece collective has an eclectic sound that swings between blues, jazz, hip-hop, rock and soul, and a maturity that belies its youth. (The band's lone EP, "Hard Times," sounds like the work of seasoned pros rather than a gaggle of barely-removed-from-high-school kids.) Even better? Wilco frontman Jeff Tweedy is slated to produce the crew's full-length debut, "Traphouse Rock," which should surface sometime this year.
