NYC's Mindless Self Indulgence giddily, guiltlessly deliver doses of electro, techno, and punk best suited for those whose hearts beat at nothing less than 160 beats per minute (which is, in case you're wondering, pretty damn fast). Still, as debaucherous and nasty as the co-ed quartet might seem, its tongue appears firmly planted in its collective cheek; the indication is that MSI are really just a bunch of sweet kids. Tonight's crazy riot of a concert, therefore, actually amounts to good, clean fun.
