Trick or Treat?
Good question. This boxset was released on American Tapes in 2006 (it's AM490 btw). It's 2 cdrs and 2 tapes. One tape is a C5 and one is a c30. Discogs and the Amtapes site has the second tape listed as a c60...it isn't. I know somebody else that owns this and it's a c30 for him as well.
The "various" adds a note of spooky confusion as well. This is the work of John Olson. Apparently he came across some horror effects material in a bargain bin, bought it for $1 and then gave it an Amtapes synth workout. The "various" is a nod to whoever was responsible for the effects material (which is presumably disc 2).
