Query: Tool's best yet

I picked up Tool's latest album the first day it came out. I had only heard one song off it but already I was impressed. anyways, after I picked up the album, just one word... amazing!!! This is definitly Tool's best yet. Everything is done right from the complex song structure and amazing riffs, right to the cool packaging. Definitly a must buy for anyone who has any interest in the band or simply music for that matter.
