Hi,
Kinda nice.
The best voice I ever heard, was a guy named "Mississipi Charles Bevel" who played on occasion with another guy named "Chic Streetman" and they were really good ... Charles had his own compositions, and I understand that he was a technician at KPFK in Los Angeles ... but his music was special and outstanding.
I have never found a CD of his work ... but his voice was so clean and clear, it was amazing to listen to. Saw him in Santa Barbara, and this was around 1980 or so.
