when i saw interpol at sonar, i thought they sounded great...was too crowded though
then i saw flogging molly/gogol bordello at sonar..(mainly went to see flogging molly) which was also sold out...and it sounded terrible (all bands) way way way too crowded, and the pillars get in the way of sight lines.
i wasn't going to buy pixies tickets because of that, but broke down since i haven't seen them before. i love having all these great shows in downtown baltimore, but many improvements could be made (also the AC system sucks balls)
