Grammy Award winning American metal band Tool has toured worldwide extensively.
Tool has performed songs by other artists occasionally in their live sets, including "Spasm" and "You Lied" by Peach, "Stranglehold" by Ted Nugent, "Demon Cleaner" by Kyuss, "No Quarter" by Led Zeppelin, and "Commando" by The Ramones.
The song "Ticks & Leeches" is only rarely performed live due to the immense strain on Keenan's voice. However, they have performed it at least a few times during their 2001 (Irvine, California) and 2002 tours including appearances in Sacramento, California, Tacoma, Washington, Fort Lauderdale, Florida, Katowice (Poland), London (England), and Berlin (Germany), with Keenan using heavy vocal effects and distortion. Tool added 'Ticks & Leeches' back to the set list for the 2012 North American Winter Tour.
In 1991, Tool played a number of small clubs in the Los Angeles, area and were signed to a major label. The two live tracks of the Opiate EP were recorded during a December 31, 1991, performance. Tool Embarked on a U.S. club tour in 1992, playing only one Canadian and one Mexican date. The band often played on a small stage, with minimal or no lighting, sometimes to only a handful of people. The set list would change from night to night, but would usually include most (if not all) of Opiate and a handful of then unreleased songs from Undertow. Some were performed with working lyrics such as "Undertow" and "Bottom".
Tool toured extensively in 1993. The band found themselves on many European festivals as well as the U.S. Lollapalooza festival. They were drawing such a crowd playing the second stage at Lollapalooza, that they were moved up to the main stage, midway through the tour. The band debuted the songs "Intolerance", "Prison Sex" and "Flood" on January 26, 1993. The set list would vary from night to night, depending on the time slot Tool was allotted, but "Sober" and "Prison Sex" were always played.
