Who are some artists you would like to hear do duets? Singers who would seem to be unlikely singing partners? Right now, I'm thinking John Hiatt and Ricki Lee Jones. I think that would be an interesting match.
Lately, my preference for a particular artist has waned and so I tend to generalize music without paying specific attention to the singers. I love John Hiatt's "Terms of my Surrender." I am not so much of a Rickie Lee Jones fan. What genre has he specialized in?
