Re: Karen Carpenter??
Good one, Klark. For a long time I always judged her drumming by her simple and tasteful work in ballads, in which she also sang. Then I saw her doing a goofy show drumming spot in YouTube and realised she had a pretty decent jazz technique - nimble and precise.
Drummers who are also lead vocalists have always amazed me. And, of course, they never compete with or down out the singer :)
