the idea of experimental seem rather a wide different from some of the names mentioned in the thread
i dig this experimental angmo fello who busker round mrt station with a big gong infront of him, knocking the gong periodically. Next time if anyone see him, spend some time, watch him from a corner, listen to the interval of his gong being hit and let it merged with the surrounding sound of the mrt, people and cars. You will hear the colours of bullshit.
