the Los Angeles Piano Quartet--pianist James Bonn, violinist Clayton Haslop, violist Ronald Copes and cellist Peter Rejto--will replace the Stuttgart Piano Trio at the Coleman Chamber Music Assn. concert, April 21 at 3:30 p.m. The German ensemble has canceled its entire North American tour.
The new program, to be heard in Beckman Auditorium at Caltech, will list Beethoven's Piano Quartet in E-flat, Opus 16, the Quartet for piano and strings by Aaron Copland and Brahms' Piano Quartet, Opus 25.
Formerly call Ko-Kela, the L.A. Piano Quartet has not performed in more than 30 states; it made its Tully Hall debut in 1984.
