The 10-man Gangbe Brass Band combines ebullient horns with chattering African percussion and call-and-response lyrics in their native Fon language. Their most recent release is the 2004 EP, Whendo, which stretches their fusion of jazz, marching brass band music and West African percussion and dialects. A full front of horns include several trumpets, trombones and a saxophone, and you can hear strains of big band music up through be-bop. They've also grown to incorporate other popular African music, echoing at times the juju music of King Sunny Ade. As they have toured the globe, more influences have turned up. Whendo even features a playful, globalized take on the raunchy Bourbon Street stripper classic "Night Train."
Gangbe make a rare four-set appearance at Jazz Fest. The band also has an evening club appearance at Rosy's with Toubab Krewe. On its self-titled debut album, Toubab crafts a deep, expansive sonic landscape of low, buzzing blues guitar, Afrobeat, reggae and cool jazz variations laid across the subtle rhythms of Malian desert blues.
