On their debut full-length, Gallowsbird’s Bark, Brooklyn-based brother-and-sister duo Matt and Eleanor Friedberger (aka the Fiery Furnaces) created a boggling blend of junkyard rock and postpunk electronica. And it sounded great. Just when you thought that they’d maxed out on forcing disparate sounds to make nice, here comes Blueberry Boat, as confusing and cool as a tangled pile of Grandma’s costume jewelry: An arena-rock solo gives way to a paisley-paved stroll right out of Magical Mystery Tour; a bluesy piano riff is joined by tribal bass drum à la Fleetwood Mac on hallucinogens. Song titles are all plants and animals, and earthy references to DQ and Super-K float into the sky on keyboard carpets. Eleanor and Matt’s matching altos spit their trademark lyrics—childhood reminisces mixed with God-knows-what—this time expanded to fill sometimes-10-minute mini-operas. Raised in Oak Park, Ill., these siblings are a testament to the hard-core dreaming that happens under Midwestern skies. The Fiery Furnaces play with Mission of Burma at 10 p.m. at the 9:30 Club, 815 V St. NW. $20. (703) 218-6500. (Anne Marson)
