I picked the Carmell Jones not too long after it came out.
I really like this set. Trumpet is probably my favorite jazz instrument. Before visiting the Mosaic site I hadn't really heard of Jones. Although he was right under my nose on Silver's "Song for my father".
I like the first two discs the best. The 3rd disc of folk songs is interesting though.
After living with the set for a while, I began to explore some of the sidemen and the arranger, Gerald Wilson. I wound up buying the Wilson mosaic too.
If you're only familiar with Brown, Byrd, Davis, Dorham, Mitchell, Morgan, etc. You owe it to yourself to add Carmell Jones to the list.
