Do you know much about Boris? They seem to have had a few stylistic changes over the years, so I find listening to them a bit strange.
I don't know a lot about them, but the main style they stick to is drone, even though every album is apparently different. One of my mates is really into them and often compares them to Melt Banana, so if you think Boris is interesting, you might want to check Melt Banana out as well. Other than that, I don't know much else.
