This is easily the most underrated. Jay Kaye was only 15 years old and traveled across the country to record it, yet it sounds better produced and played than the majority of psych rock coming out at the time. He got screwed over by his label when they chose his 35 second intro track, which is just an abstract synth improv, for the only advertisement spot the album got. It was virtually unheard until the 90s when it got rereleased, but it's still criminally underrated. Very highly recommended.
