The Orb Live
 

Saw the Orb play last night in Seattle and it was a fantastic show! One of them 'DJs' while the other runs a 20+ channel mixing board, mostly improv as I understand. The set itself was rough around the edges, but they were professionals about the whole thing and laughed every mis-step off and were generally having a great time. If they are making a stop near you I can't recommend them enough.
