Let's see if I get everything right (and correct me if I'm wrong !)... Kenneth Anger had already an actor for the main role in his movie when he saw Bobby Beausoleil with his band The Orkustra in a happening in San Francisco. He convinced Beausoleil in being his Lucifer on the condition that Beausoleil and his band write and play the soundtrack. He then lended money to Bobby Beausoleil to buy musical equipement but Beausoleil bought drugs instead. Anger then told Beausoleil to keep the drugs but leave. Beausoleil left with the drugs AND some of the reels of "Lucifer Rising" that had been already shot (according to Beausoleil, he didn't steal anything and Anger simply lied because he had run out of money to end the movie). The Orkustra broke up, Beausoleil did only one gig with his new band The Magick Powerhouse of Oz, and left to San Francisco. While in California he fell upon Charles Manson's 'Family' at Spahn Ranch (apparently not willingly, according to Kenneth Anger). Bobby Beausoleil then killed Gary Hinman (maybe under Manson's influence), a drug dealerhe'd believed to have sold him duff mesacaline. According to Kenneth Anger again, Charles Manson himself buried the "Lucifer Rising" reels in the desert so that they get destroyed by the heat. Kenneth Anger tried to build upon the rushes left of the movie and finally released "Invocation of my demon brother" with a soundtrack by Mick Jagger who improvised whiletrying to master the moog he had just bought... Later Anger re-shot parts of the movie with Marianne Faithfull (in full heroin-addict condition) and Chris Jagger (Mick Jagger's brother) with whom he didn't get on well and of whom he finally erased all acting contribution in the movie. "Lucifer Rising" finally went out in 1973.
In 1972, The Ventures did 3 LPs in only one year... This one is their second. Trying to deal with the change in tastes that was pushing them towards oblivion, they experimented a lot: on this one they try covering songs that are far away from their usual grounds (blaxploitation soul-funk with Isaac Hayes' "Theme From Shaft", hippie folk stuff with Cat Steven's "Peace Train"). They also try new sounds by adding keyboards, horns and strings. Add to that that they wrote 5 of the tracks themselves, which is a lot for a band that usually plays mostly covers (the track "Tight Fit" down below is one of them). The result is pretty strange when considering this is a Ventures LP, but I think it works fine enough to make it a very good instrumental record. Of course, the sales were a disaster and this LP 'topped' at 196 in the U.S. charts (the next one didn't even enter the charts).
Try it forgetting it's a Ventures record, don't expect any R'n'R fuzzy sounds, and you'll be amazed by their ability at producing highly enjoyable melodies ! (Gosh, I never wrote so many words !!!)
(Sorry if this is quite misleading, but 'Biker Movie OST' is the closest I found in the labels !)
Very good compilation of supposedly x-rated afro-american movie soundtracks... Yet it seems like these tracks are actually a lot more recent than this (read the youTube commentaries of the video for more info).
