I don't know if I would spin that more than once, but it was pretty cool (the song - not the video). That dude (Greg Fox is his name I think?) used to play drums in Liturgy. That was a lot better than Liturgy IMO, I saw them once and he was great but overall as a band they were tedious.
I liked this a lot.
I've heard people talk about the connection between free jazz and black metal/extreme metal... that Guardian Alien stuff makes the connection more explicit.
