Electric Jalaba + Seeds of Creation + The Annie Whitehead World Music Workshop +

The Vortex's twenty-fifth anniversary celebrations take place in an all day event featuring Algerian jazz-fusion band SOC, the busy and ever-enjoyable jazz, ska and session trombonist Whitehead, and clubby fusion octet N77, who mix funky breakbeats with raw improvisation that recalls British jazz of the '60s and '70s.
