The Shit Hits the Sheds was a concert tour by the American heavy metal band Metallica, which took place in 1994.
On the last date of the tour in Miami, the famed lead vocalist of Judas Priest, Rob Halford (who at the time was the lead vocalist for Fight), sang guest vocals on stage for a performance of "Rapid Fire" from his band's 1980 album British Steel.
The supporting acts for this tour were Danzig, Suicidal Tendencies (whose bassist Robert Trujillo would join Metallica nine years later), Candlebox, and Fight.
Candlebox were a replacement for Alice in Chains, who were forced to withdraw from the tour due to lead vocalist Layne Staley's heroin addiction.
[1] The Offspring (who had just released their breakthrough album Smash) were originally invited to replace Alice in Chains, but declined due to their desire to continue playing in clubs as well as logistical issues.
