Elektra Records A&R director Michael Alago, and co-founder of Q-Prime Management Cliff Burnstein, attended a Metallica concert in September 1984. They were impressed with the performance, signed Metallica to Elektra, and made the band a client of Q-Prime Management. Metallica's growing success was such that the band's British label Music for Nations released "Creeping Death" as a limited edition single, which sold 40,000 copies as an import in the U.S. Two of the three songs on the recordcover versions of Diamond Head's "Am I Evil?" and Blitzkrieg's "Blitzkrieg"appeared on the 1988 Elektra reissue of "Kill 'Em All". Metallica embarked on its first major European tour with Tank to an average crowd of 1,300. Returning to the U.S., it embarked upon a tour co-headlining with W.A.S.P. and supported by Armored Saint. Metallica played its largest show at the Monsters of Rock festival at Donington Park, England, on August 17, 1985, with Bon Jovi and Ratt, playing to 70,000 people. At a show in Oakland, California, at the Day on the Green festival, the band played to a crowd of 60,000.
