As a lifelong fan of Rush and Pink Floyd, my ears have recently been opened to TOOL. Of course, I have heard a couple songs over the years (e.g. Sober, Stinkfist, Schism), but I had no idea the band was this deeply talented. I think I now can name three bands that meet my lofty standards. Pneuma and Eulogy are on constant loop. It's a whole new world.
