not sure what to call this...

OK, here's a strange question, I hope.

I was just listening to some opera, and had a minor prog revelation: there are a number of excellent female vocalists in prog, with perhaps a tendency towards sopranos.

There are lots of male vocalists, again with perhaps a trend towards tenor, or even higher

Are there any female contraltos? What first hit me: are there any male baritones, or even basses?

Inquiring (OK obsessive) minds...
