Tool is playing Izod Center in NJ on February 1st. The promoters are advertising it as their "only area appearance" and tickets go on sale Saturdy at 10am which is also when tickets go on sale for 1/31 at Mohegan Sun in CT.
Coldplay also has a show coming up at the Izod Center, and actually they have two. They just added August 4th to their schedule that already included August 3rd. Tickets for both go on sale Saturday at 10am too, but there's a presale going on now with password "blues".
