Well,i remember a performance of Jorge Lima Barreto (Portuguese electronic/free jazz) playing with a saxophonist with 2 microphones, one normal and the other with a brutal delay. He would play on the normal microphone and sometimes he directed the instrument output to the delayed microphone and it sounded monumental. Not sure what musician he was, i think is Tomas Stanko, but not sure. The performance sounded like you went through a big storm. :D
