Monsters of Rock '88 is the second time American heavy metal band Metallica would embark upon the Monsters of Rock tour festival, their first time with new bassist Jason Newsted. While short it would feature the live debut of Leper Messiah. New cover songs would also make their live debut such as Crash Course in Brain Surgery (originally by Budgie), The Small Hours (originally by Holocaust), and The Wait (originally by Killing Joke), all of which are on the Garage Days Re-visited EP which would release in the middle of the tour.
