As a practicing Eastern Orthodox Christian, this Jesus music might be a subject I know a little something about, though my normal preference is more Byzantine, Arabic or Slavonic and dates back to at least the 5th Century rather than the 20th. Still, give mad respect to Subliminal Sounds for digging up all these odd Christian psychedelic gems and putting them into one stunning collection.
For those with a bit more coin to spend, there is a book/magazine package that runs for around US$70, and it looks to be well worth it.
