Music Appreciation

There is a song in the "Sign O' The Times" concert movie where she comes out from behind the kit to do a rap thing in the middle of the song.
As she is doing that, Prineville takes over a drums. After she's done, the cameras are on neither of them, and there is an obvious difference in the level of drumming. A few seconds later the shot changes and, sure enough, Sheila is back behind the kit.
Not that Prince didn't do a fine job, but she was quicker, with more pop, and more powerful.
She's extremely good the whole concert, but that song really cemented how good she was.
