A concert with Gregory Biss and friends will open EAC’s annual Concert Series at 7 p.m. on July 1. The program will include piano music by Bach, Mozart, Schubert, Glass & Biss. One of Biss’ compositions on the program, “Routes”, was written more than 50 years ago and features piano and trombone, both of which are manipulated electronically in live time. Jane Lanctot, piano, and Gene Nichols, trombone, will join Biss for this piece.
