What makes a true Guided By Voices fan? Someone who has all the albums? Knows all the various players? Thinks the band lost its way in 1997 by signing with Capitol Records? Mourned the "disbanding" in 2004 and celebrated the return in 2010? Who the hell knows? You do, if you are one of those fans; the rest of us might have a passing familiar with one or another of the many, many records or even have heard the early lo-fi stuff and thought it was cool - or not. They're coming back to town to play Headliners on August 30, with Bobby Bare Jr. on the tour. The latest (as of this writing) is Cool Planet. Tickets are $23 adv/ $25 DoS.
