AIC + Tool = Sweet

I found these files on The Tool Page. Though Alice In Chains will be touring this summer with Comes With The Fall's singer William DuVall, these live tracks with Tool's Maynard James Keenan on vocals give a taste of what might have been. The sound quality on these isn't great, but it's still a worthwhile listen.

Also on The Tool Page is this MP3 of Maynard singing a duet with Tori Amos on her "Muhammad My Friend" at Madison Square Garden on 01-23-97 .
