A collection of 35 songs by the late freak-out rock experimenter Frank Zappa,

entitled Mystery Disc, is on shelves now. The album features 25 tracks that are

from 1985-87, entitled The Old Masters. The tracks on the collection include

"Original Duke of Prunes," "The Village Inn," "Plastic People," "Agency Man," "Chucha,"

"Harmonica Fun" and "Boss Nova Pervertamento."
