According to dirtyrockstar on Toolarmy, he heard them saying that Tool would be on tour soon on 97.1 (FM I presume) in Dallas. Apparently the station will be giving away tickets.
Not too sure about this to be honest. I’d like it to be true, but I don’t know that I’d expect Tool to tour again until after a new album had been released. Unless of course they’re recorded something in secret and will surprise us NIN style, but I kinda doubt that too.
