Plenty to do this weekend... I mean, in a perceivably less productive manner than cleaning your house or raking leaves - you could go out to plenty of bars, Pontiac or Corktown included, to see some bands.
But in terms of seeing some considerably freakier live interpretations that would be hard to find elsewhere - try the sandwich of Jesus and Chainsaw Massacre and Marco Polio & The New Vaccines - at the Belmont Friday - (the latter of the two will reprise their Halloween Yeah Yeah Yeah's set).
or at the Crofoot later on - 11/20, with Carjack and goLab! (look for some forthcoming releases from the former)
