These older Baritone players mentioned above sound wonderful to me. I was born in 1963, grew up in the 70's-80's listening mostly to the rock and roll/metal of that time. I came to like jazz when I turned 40. Since then I have bought over 400 jazz cd's, 2/3 being the older stuff and 1/3 musicians active now. Living just 1 hour from NYC I get to see a lot of the active jazz musicians live. I would have to ask the members posting about Baritone players why James Carter was not mentioned. I have seen him live 5 times, own every cd he recorded, and he is simply incredible on Tenor, Alto, Soprano, and Baritone, which I believe he won best Baritone player a few years ago (not sure which) by Down Beat Magazine.
