My favorite Porcupine Tree: On the Sunday of Life... (1991) Back when Steven Wilson was more tripped out Floyd and less neo-prog-metal.
Country Joe & the Bevis Frond - 1998 - Eat flowers and kiss babies (live, great sound though. It also has the best version of Bass strings I've heard)
Earthless - 2007 - Rythms from a cosmic sky Awesome heavy psychedelic jam rock! Gonna see them finally in april
