Bassist and singer Devin Alexander attributes The Post Mortems' two-instrument setup to laziness, but it's not ordinary laziness - as there's very little that's typical about the Quad Cities/Iowa City band.

From its bass-and-drums-rock conceit to its gear to the seven-plus years it took to record its new album Cracked & Crooked, The Post Mortems have often traveled through bramble and brush.

But as arduous as that has often been for Alexander and drummer Al Raymond, the band's March 7 album-release show at RIBCO should provide plenty of proof that the journey has borne fruit. The record successfully hews to The Post Mortems' two-man core while pushing past the boundaries of what should be possible with only a traditional rhythm section - maintaining a minimalist identity while giving listeners much of they dynamic range and texture they expect from a larger outfit. And Alexander said his recently debuted live bass rig should be a revelation to longtime fans of the band.
