If you don't know Hash Jar Tempo, you owe it to yourself to check out Well Oiled from 1997. It's a collaboration between Roy Montgomery and Bardo Pond, and is a long suite in seven movements. Supposedly just a sample of a seventy-minute session which was improvised in 1995. If you love that instrumental psychedelic rock, this is the real buzz, formed from the groundwork by the Velvet Underground, Pink Floyd, the Doors, Hawkwind, and other visionaries in the psych world. I also have Under Glass from a couple years later, which is very good too, if maybe just a small step below and a bit more experimental.
And on the more pop side, you know how much I love the new Voyager One Dissolver
