Tool broke out their 1993 track "Undertow" for the first time since April 2002 during a March 3 show at the Little Caesars Arena in Detroit, MI. Which is awesome that Tool is still making their live shows an event and not playing the same thing every night (not that there's anything wrong with that either).
You can catch Tool at one of the dates below, and check out their re-work of "Opiate" here.
