Experimental Music In Sanders Tonight

David Tudor and John Cage, two leading exponents of the "experimentalist" trend in American music, will give a concert at 8:30 p.m. tonight in Sanders Theatre.

Tudor, a pianist, will perform a number of modern American and European works, including two of Cage's compositions. Cage, who will join him on a second piano for the world premiere of Cage's "Music for Two Pianos," has been lecturing on musical concepts.
