Kinda been thinking about this. Other than all-girl groups like The Bangles, The Go-Go's, The Runaways and the like, I'm hard pressed to think of too many groups that have female instrument players. There's plenty of female solo artists who play an instrument, but I can hardly think of any that are just part of a band. Can you name any?
Extra special bonus points for a group containing a female lead guitarist or drummer. There's a bit of a cliche about female bassists (I'll....leave it to you to figure out), but certainly list those, too. I'm not too interested in keys/piano players either, but if you know of any do go ahead and list them.
Truly the only example I can think of on my own is The Smashing Pumpkins, D'arcy Wretzky and Nicole Fiorentino as bassists.
