Toolshed are reporting that the lineup for the Bonnaroo Festival in Tennessee was leaked last night, and that Tool were on the lineup. If this is true then it should be confirmed in the next few days.

3/31 Baton Rouge, LA @ River Center
4/2 Pensacola, FL @ Pensacola Civic Center
4/3 Tallahassee, FL @ Leon County Civic Center
4/5 Tampa, FL @ USF Sundome
