My aunt and cousin are in the BYU Gamelan Bintang Wahyu Ensemble, and they had a show recently that I went to. I think the Gamelan Bintang Wahyu is from India. (edit: It is from Bali, not India. Thanks Aunt Myrna for the update!) Anyways, it was a very interesting show.
Their performance was followed by the BYU Panoramic Steel Orchestra. I have not been to a steel orchestra performance before, and it blew me away. Ten or fifteen drum sets sounded like a full orchestra! Wow. I don't know how to explain it, but the sound is surprising and amazing.
