Bobble Tiki would describe Seattle popsters Crystal Skulls as what it might sound like if Steely Dan and Stereolab were to get in a bar fight. Their sound sits somewhere between '70s AM radio gold and indie pop.  The Skulls played the late Sunday afternoon slot on Bumbershoot's Backyard Stage giving the mostly lounging crowd a little snap, jangle and pop. â€" Bobble Tiki
