Go here for a post about the April 4 and 6 Network for New Music concerts that will be discussed on Saturday’s “Crossover” program on WRTI-FM. I spoke with host Jill Pasternak earlier this week, and Uri Caine will also comment. The program can be heard Saturday morning at 11:30 am on WRTI-FM, with an encore Friday evening at 7 pm on WRTI-HD2. Both airings are available on the All-Classical stream at the WRTI website. UPDATE: go here for the stream of this edition of Crossover.
