Yeah, Triptykon is a cool record.
He also cut some heavy sides with Juhani Aaltonen for Blue Master and a solo LP that are all very scarce and deserving of reissue. Nan Madol on Japo is real nice, as is another weird one-off Norwegian psychedelic fusion date called "Ode to Marilyn." Excellent player and sorely overlooked, but the reissue market being what it is... probably not surprising.
