This EP contains a 6 hour song. 25ish minutes in and it's clear that it's pretty much a huge jam of epicness. I believe the proceeds are going to charity, but... I would be 100% ok with giving this band many dollars for even a 6 second song. If I had to pick a song that it resembles so far, it'd probably be Yoshimi Battles the Pink Robots Pt. 2 (I think it's part 2, anyway.. the instrumental)

If you aren't familiar with the band, they're a Psychedelic/prog-rockish kind of band.
