Probot
Biography
Dave Grohl has voiced his appreciation of heavy metal numerous times over the years, whether it be trying to convince his Nirvana bandmates to have Sepultura open shows on the In Utero tour or playing with the Foo Fighters alongside Slayer, Pantera, and Black Sabbath at Ozzfest 1998 in the U.K.. But he was never so exuberant about his metal fixation until he issued the all-star project Probot in the early 21st century. As a teen growing up in Washington, D.C., during the early '80s, Grohl and a friend became interested in such (then) cult metal bands as Iron Maiden and Motörhead, before discovering a mail order ad for a record service named "End of the Rainbow," which specialized in tracking down the newest releases from the metal underground. Looking for bands that were "fast and heavy," the duo found their gold mine when they heard such classics as Metallica's Kill 'Em All and Mercyful Fate's Melissa. From there, Grohl continued to hunt down further releases from the metal underground, which led to an appreciation for such groups as Trouble and Celtic Frost, even though he was playing in hardcore bands at the time.
As just about any rock fan knows, Grohl spent the '90s playing with two of the decade's most successful alternative rock acts, Nirvana and the Foo Fighters.
