Tim Kasher really lets it all hang out. As the co-founder and lead singer of Cursive, an Omaha-based indie group that’s been around since 1995, he alternates between waxing poetic and cursing the heavens, with a little spit thrown in for good measure. He’s an odd vocal hybrid of Jack White and Connor Oberst, but a better singer than both men combined (not saying much, but it’s noteworthy). As if he needed to stand out from his contemporaries any more, he also plays the organ.

Cursive could easily be a one-man show, but the group has no true leader—each member is an unconnected part in a quickly moving machine. Kasher, with all his swagger and lyrical pyrotechnics, is well-matched by co-founding bassist Matt Maginn and longtime guitarist Ted Stevens, who’s been with the group since 1999. Along with drummer Cully Symington and pianist Patrick Newberry, the "arrangement" is essentially chaos--each member plays a tune of his own, independent of (and often in contrast with) his bandmates. At times, even the drumbeats follow a completely independent course. If this all sounds cacophonous—well, it can be. But most of Cursive’s instrumental work toes the line between grunge and elemental prog-rock without going too far in either direction. 

Cursive’s forthcoming release, I am Gemini, will be available on Tuesday, Feb. 21. This is the band’s seventh release, and a hotly anticipated follow-up to 2009’s Mama, I’m Swollen. You could wait until Tuesday to hear the new album, or go down to Neumos tonight and see this Frankenstein monster in the flesh. Tickets ($15) are available online, and doors open at 8 p.m.
