I've never heard of them and anyone who knows me wouldn't find that the least bit surprising. I did, however, just watch 4 of their videos on You-Tube. I didn't actually see "a band" at all, just some ugly girls writhing around as if they were having a series of grand mal seizures.
Call me old fashioned, hell I am old fashioned, but I believe a band either straps on, holds onto, or sits behind, instruments and plays.
Wriggling around and lip syncing does not a band make.
