It always amazed me that Lux was able to make tapes like these back then with all analog equipment. Today, I can wip up a compilation like this in a few hours (not counting the time it takes to pick the songs, and trailers, etc) on my computer (see my May 29th posting). It must have taken him forever to do this back then.
So legend has it that Lux made this tape. Then it got into the hands of some bootleggers, and they pressed it to vinyl.
Its a classic of its kind and is partly responsible for me making compilations all the time.
If you dig this LP, do yourself a favor and track down the compilations called MELLO JELLO. Basically the same idea, great music mixed with exploitation trailers. 2 volumes with a 3rd on the way (although it seems like its been delayed indefinitely). Also of note is the WAVY GRAVY series of LP's. Same idea...
