Heavy music was my first love. I wasn't really interested in music at all until high school, and it was Tool's AEnima that finally did the trick.
Of late, I've really been into the work of Ben Sharp, who records under the name Cloudkicker. Complex, layered, angular, odd-time, HEAVY guitar work that nevertheless has a great sense of warmth and spaciousness, making the whole thing feel quite majestic. This stuff hits a lot of my ambient buttons, but in a very different way. There's a subtly-infused indie sensibility and a weird sort of nostalgia that accompanies the proceedings. All the heaviness aside, this is some of the most beautiful music I've ever heard. And, it's all instrumental, so no angsty grunting of pre-teen caliber poetry here.
