In a punishing set at Washington, D.C.'s Capital One Arena, prog/metal gods Tool (singer Maynard James Keenan, guitarist Adam Jones, bassist Justin Chancellor, and drummer Danny Carey) delivered two-and-a-half hours of churning, polyrhythmic insanity. Touring behind this year's long-awaited Fear Innoculum, the all-inclusive setlist highlighted how complementary the new songs are with the back catalog. "Fear Innoculum" the song was paired with "Aenema" to kick things off, and things just got heavier from there.
