Imho this long, hitherto unknown looped version of “Black mass” by Jason Crest was secretly cut to acetate for private use (a séance, a projection) by some crafty engineer (with a penchant for occultism) who was working at the studio at the time … The short (regular) version can be found on the B side of the “A place in the sun” 7″ (Philips UK 1969-08) or more easily via the “Rubble Four The 49 Minute Technicolour Dream” v/a lp (Bam-Caruso 1984 or 1986, KIRI 027) or “The Rubble Collection 2” v/a cd (Bam-Caruso 1992, cat. no. RUBBLE CD 2); all “Rubble” volumes have been reissued by Past & Present on cd and lp a couple of years ago, incidentally. The hidden track after “Wasted ground” is “Merry go round” by ? (unknown acetate). All of the tracks on display here are off the brand new “Psychedelic Schlemiels 4 More Lost Sounds From The Britpsych Scene 1966-1969” v/a cd (Wooden Hill 2010, cat. no. WHCD031).
