It's not the kind of music i'm the most listening to myself but it happens that i'm actually playing in a brass band :)
so let me recommend a few bands that we know and we like in that genre...
let's start with our friends :
LaBrassBanda from Germany just released a new nice album called Übersee. Sorry no tracks to play there yet... you can listen to Brassbanda "Live", a live recording... the album really sound great
The Hungry March Band from New York.
The Express Brass Band from München. Their album Oriental Journey is quiet good, with a good mix of Rahsaan Roland Kirk, Pharoah Sanders and Afro Beat on some tracks.
My own is Samenakoa from France. Have a listen to Everyone or The March on the album The March. :)
and other brass bands i like :
Mardi Gras.BB. so much good tracks from that german brass band and the sound is sooo good :)
Youngblood Brass Band. Sell Me More Or Like You Just Don't Care
