The Go-Gos, The Bangles, Karen Carpenter, Irlene Mandrell, Melissa Etheridge; none of them impress me very much as musicians. The only ones I can think of that are any good are the drummer with Lenny Kravitz (I don't know her name) and Bonnie Raitt.
I think it is one of two things, or maybe a "Combination of the Two." (Extra points for the name of that artist.) Either they don't have enough testosterone, or the fact that most females start with instruments such as piano, clarinet or violin, then when they get into a band, they take up drums or guitar.
Your thoughts?
