Bands that are psychedelic in the TOOL way?

I know they're not usually called psych rock but I would argue their sound is way more psychedelic than something like The Doors (love them too). Mainly something that has that dense multi-textured atmosphere, the transcendent/out of body feeling, and possibly some eastern influence from Indian or middle eastern music. There are few bands that I think are close, most being post rock/metal like Neurosis and Oceansize, but I think TOOL is much more psychedelic than either.
