Mode Records has etched its name in the annals of music history, producing the avant-garde and modern classical music of influential composers such as John Cage, Morton Feldman, Iannis Xenakis, and Harry Partch. In its twenty-fifth year, they are hosting a six-hour benefit concert featuring very special performances by Philip Glass and John Zorn and a rare performance of John Cage's "Concert for Piano and Orchestra" with "Aria."
