Karen Carpenter as a drummer

I am a young music fan who has just recently found time to start aquainting himself with the Carpenters. (I know it’s late, but remember- I am young and didn’t get a chance to experience the music the first time around!)

Anyway, I’ve just started off with a very sparse incomplete hits compilation. There are only a few tracks on which Karen plays drums. There’s not really enough for me to form an opinion of her as a drummer. So, tell me.

How was Karen as a drummer?

Is there anyone out there in messageboardland who had a chance to hear them in concert? I’m under the impression she did more drumming for live performances, although I may be mistaken.

How much drumming did she do in the studio?

Are there any good concert recordings available on CD?

Just looking to further my appreciation. Let me know what you guys think!
