Normally, I'm not one who goes for gimmicks in music. I find them tacky, and mostly useless appendages that try to mask a band's deficiencies. Taking a cookie-cutter band and dressing them up in stupid costumes, or writing lyrics about only one subject, doesn't make them any more special. Gimmicks usually expose the band's shortcomings, because the obvious facade only draws attention to their perceived need to distract. I can think of very few bands with a gimmick who have managed to keep my interest, because a gimmick alone is going to get old after a while. Yes, even if you're GWAR.
