Metal Man Has Hornet's Wings

Most of this record is from a radio show on KWST radio, 01-Nov-1975, where Zappa and Beefheart played oldies and oddities. The bootleggers have added a few tracks (the ones that seem out of place). (There is a completely unsubstantiated rumour that this radio show was actually a broadcast of a Warner Brothers promo record with these songs on it, which has never been found and never been confirmed to have existed.)

Tracks 1, 7, 14 and 16 have been officially released on Mystery Disc and Captain Beefheart's Trout Mask Replica.

As for the other tracks:
* Track 2 (and maybe track 3) are live at the Shrine Auditorium, Los Angeles, 24-Feb-1974 (?)
* Track 4 has Zappa talking about a record company's reaction to a demo tape, while two songs are playing in the background: "Power Trio from the Saints & Sinners" and "Bossa Nova Pervertamento", officially released on the Mystery Disc
* Track 5 is the last Studio Z recording (1964) from the night before the police raid (with van Vliet?)
* Track 6 has been officially released (perhaps in a shorter edit) on the Mystery Disc (as "Original Mothers at the Broadside (Pomona)"); it is the first live recording of the Mothers, 1965, and the song they are playing is called "Louisiana Blues"
* Track 8 is a 1966 recording of Lowell George & the Factory, produced by and featuring Frank Zappa, officially released on the album Lightning-Rod Man in 1993
* Track 9 is the 1969 single version from A&R Studios, New York, a different edit of which has been released on Stage #5
* Tracks 10-11 are from Studio Z in 1964. Track 10 is an early rehearsal recording of the Mothers, with Zappa talking on top of it - he claims the group is trying to play "Rock Around the Clock" by Bill Haley.
* Track 12 is from the first studio rehearsal with the Mothers, 1965
* Track 13 could be live 1968
* Track 15 is live in London 1968
