Tool's probably the band I've listened to for the longest time. I got into them in middle school/late elementary (can't remember really), though I could not obtain any of their CD's at that time (parents). However, I was able to obtain a huge chunk of their discography in the 10th grade, and to this day, they're one of my favorite bands.

I was actually going to see them in concert last summer, but due to conflicts, I could not attend. Needless to say, I was pissed, and it didn't help any that I've heard it was an amazing show.

Lateralus is probably my favorite album by them, though Ænima is up there. I don't have a favorite song by them. Just a favorite album.
