Concert that’s free for music students under 22 (but alas not for the rest of us). The group is called ETHEL, and the venue is the Gild Hall in Arden. Read more about the concert at http://www.ardenclub.org/concerts.htm . Besides music of Glass and Riley, one work they are playing involves Tibetan prayer bells, another uses an invented instrument handmade of wood called the “daxophone” (no it is not a typo). Because of a major grant for this show, they’re offering FREE tickets to music students in the region (under 22). If you’re under 22 and interested in free tickets, email Ron Ozer at firstname.lastname@example.org. He’ll put you on the Will Call list.
