Minnesota-based art rockers Cloud Cult have principles. Since musician and environmentalist Craig Minowa founded the band in 1995, the Cult have scorned lucrative record deals in favor of their own not-for-profit label, released albums made entirely from recycled materials, and even planted thousands of trees to offset their carbon footprint. But Dave Matthews Band they're not: the group's propensity for baroque balladry, sweeping strings, and rich choral arrangements is more in line with Arcade Fire's pathos-drenched anthems or the Polyphonic Spree's many-membered chamber pop. Tonight, the septet — with eco-friendly pamphlets, video backdrop, and live painters in tow — performs tracks from its sixth LP, Feel Good Ghosts (Tea-Partying through Tornados).
