We've said it before and we'll say it again: Phoenix's historic Orpheum Theatre is used far too infrequently for concerts. Okay, so the city-owned theater's vending requirements make the booze lines way too long for concert promoters to make any real money staging rock shows there. When it actually happens, it's magical. Such was the case with Wilco frontman Jeff Tweedy's December solo show at the theater. Playing through much of his band's catalog while tossing in a few covers and rarities, Tweedy mesmerized us all the way through an amp-less and acoustic closing number that relied on the theater's stellar acoustics. Tweedy and his band play Phoenix far too infrequently, but this show, supposedly an excuse to visit his sister's family, more than made up for it.
