During his last years, Frank Zappa concentrated on his "serious music," trying to impose himself as a composer and relegating the rock personality to the closet. His last two completed projects topped everything he had done before in this particular field. The Yellow Shark, an album of orchestral music, was released only a few weeks before he succumbed to cancer (the computer music/sound collage album Civilization Phaze III was released a few months later). This CD, named for a plexiglas fish given to Zappa in 1988, culls live recordings from the Ensemble Modern's 1992 program of the composer's music.
