One of the qawwali pieces that I will play on Monday's Sangam show is by the Brooklyn Qawwali Party (formerly known as Brook's Qawwali Party). I came across them on the All Things Pakistan blog. There is an interesting discussion there about their music. Some of the people have commented that BQP's sound is like a shaadi-vala band.
BQP is essentially a group of jazz musicians who have been influenced by Nusrat Fateh Ali Khan's music and are producing music that combines elements of jazz and qawwali. I love their sound. They haven't released a CD yet but I contacted them and Jesse Neuman generously sent me a couple of tracks, one of which I'll play on Monday and the second one on another show. BQP performs around the New York area and would probably be willing to travel if invited. You can read more about them here:
