It’s rare to find a drummer that sings in any sense beyond just a background vocal. And it’s also rare to find a female on the drums.  Of course there are the handful of well-known exceptions to both of these generalities, but “rare” is still an accurate term.

And then you have Karen Carpenter… doing both.  I mean, she doesn’t suck.  Maybe not a significant influence on the evolution of the drumset, but she’s getting the job done for sure.
