Morton Feldman's last composition, Piano, Violin, Viola, Cello, was completed in 1987; although its instrumentation largely corresponds to that of Piano and String Quartet, with one instead of two violins, it differs in almost every other respect from the composition written only two years earlier, for here, in contrast to Piano and String Quartet, Feldman makes every effort to integrate the piano into the string section, and the basic formal components of the composition are no longer staves, as they were in Piano and String Quartet. Double LP with 4th side etched.
