Brouwer concerto premieres

My wife and I just got back from a Sunday night performance at Rocky River Presbyterian Church of CityMusic Cleveland, the last of a series of five concerts premiering Margaret Brouwer's new violin concerto (they also did Stravinsky's "Danses Concertantes" and Mozart's 39th symphony). I thought the Brouwer piece was really good, maybe her best so far. The use of percussion in the piece was interesting; during the first movement, the percussion played an instrument I didn't recognize, which Brouwer explained is a "Chinese opera gong." A press release has claimed the piece had elements of trip hop; that sounded strange to me, but sure enough, in the second movement the percussionist played a rhythm on the drums as the violin soloist played, and it did sound a bit like Portishead. Brouwer says a recording of the piece will become available later; more details when I have them.
