Tool

Art-metal juggernaut Tool has kept relatively quiet in the years following 2006's 10,000 Days, only popping up occasionally, as frontman Maynard James Keenan has busied himself with winemaking and a pair of extracurricular bands: A Perfect Circle and Puscifer. Hopefully tonight's surprise-attack appearance by contemporary prog's finest means that LP No. 5 is on its way before too long.
