Not necessarily making supergroups, just bands that you'd like to start, or to see, or to know existed.
Jpeg and the Gifs (I call dibs on this name. I've copyrighted it. I might use it some day. I still can't decide if it would be a novelty band about the "early days" of the internet before the dot com bubble burst, or if it would just be a total straight-faced garage rock band in the Little Steven manner)
No Rimbaud!: I've also thought about starting this band called No Rimbaud! It would be like a meta-hardcore band. There would be extended sxe hardcore style between-song monologues about things that suck and then all the songs would sound like Tiny Tim or the worst Donovan ("Riki Tiki Tavi" or "I Love My Shirt"). In fact, maybe they're just Donovan covers. But not in hardcore fashion. It's like a ukulele and a bongo. But anyway, the "No Rimbaud!" title comes from the band's moral position, which asserts itself as a reactionary refusal of Patti Smith, her pseudo-intellectual variation on proto-punk, and all things Bacchanalean, self-indulgent, decadent; including the idea of being defiant itself. This, of course, is a problematic position for the band to uphold because of its own self-indulgent and defiant tirades about the excesses of the Punk generation, not to mention the obvious stoner roots of the Donovan-type stuff it's always playing.
Seriously, y'all better not steal my ideas.
But what have you guys got?
