Diabolic pressure.

bringin' ya' down.
Killin' ya', killin' ya', killin' ya', killin' ya', bringin' ya' down.

Notes from David Chance:
According to the Howard DeWitt book (The Mystic's Music), this song was recorded (along with a number of others) at the Record Plant in Sausalito, California in June 1975 (DeWitt, page 72) [Ed: eventually surfacing on at least the vinyl bootleg Please, No Moke!]

The musicians involved were most likely (from notes in San Francisco newspapers at that time, i.e. circa the Great American Musical Hall concerts April 18-21, 1975) Mark Jordan (keyboards), John Blakely (guitar), Tony Dey (drums), and David Hayes [definite...see the lyric transcription above] (bass)...there is a back up vocalist(s) present, unknown, but probably one of the aforementioned.

The song clocks in at 8 minutes exactly...there's a fade-out at the end which suggests this was probably intended for release on a commercial album...perhaps a re-working of the "Mechanical Bliss/Stiff Upper Lip" album which was twice scheduled for release in 1975 but got scrapped.
