Kronos Quartet/Frank Zappa - Excerpt From Thirty Pieces For String Quartet/4'33" (1993)
General: There are no catalog number, no information about release year or release country. Both tracks are from the album: A Chance Operation - The John Cage Tribute. This album was released in 1993, so I asume the cassette was released in 1993 too.
