Final Kraft

A gong is suspended from the ceiling of Avery Fisher Hall. Several rows of seats have been removed to make room for a liquid-nitrogen canister and other unconventional percussion. Magnus Lindberg's Kraft — a glorious sonic assault inspired variously by Stockhausen, Xenakis, Boulez, and Einstürzende Neubauten — has the last of three performances on Tuesday night at the New York Philharmonic; a few dozen seats remain available. The orchestra reports that it has received a very irate letter from a longtime subscriber who attended the Philharmonic last Wednesday night and was upset to find that Kraft did not appear on the program.
