Great stuff, the oversight of Kaleidoscope is indeed a crime. I only have
Tangerine Dream but it doesn't have a dull moment and has always been one of my favourite psych albums - each track is literally an anthem...
I guess their abstinence and dedication got them left out of the fun and games at the UFO Club/psychotropics clique. Shame. Plus
Tangerine's cover art is pleasingly similar to my favourite of all time,
Rubber Soul 
Anybody who is reading this listen to the man and seek out the band, they're are all over the blogs. Will have to check out this second album now, never thought to see if they did one!
Great selection of blues videos you posted as well, lots I am not familiar with. Sometimes the blues seems one of the only pure and uncorrupted forms of music... are you familiar with Skip James?
