Im gonna guess that given the number of Sousy haters, not alot of brass band fans here.
It's sad really. Maybe check out Nat McIntosh, especially his work with Youngblood Brass Band.
other bands worth checking out:
Mama Digdown, Soul Rebels, Rebirth, New Birth, Dirty Dozen, Hot 8, Inner City All Stars, Critical Brass, Jack, Stooges Music Group, and Free Agents.
