Yeah, 100% Pink Floyd until the melody/solo came in. haha The likeness was uncanny. Slayer still sounds like crap in my opinion, sounds way too electronic and has no bottom end and crunch.
I see this as more of a loop than an actual song since it's the same chords the whole time. This would be a sick loop though.
Even though they're fairly simple, I still like the drums a lot, you got a great sound out of them.
