The term "thrash metal" was coined in February 1984 by "Kerrang!" journalist Malcolm Dome in reference to Anthrax's song "Metal Thrashing Mad". Prior to this, Hetfield referred to Metallica's sound as "power metal". In late 1982, Ulrich and Hetfield attended a show at the West Hollywood nightclub Whisky a Go Go, which featured bassist Cliff Burton in the band Trauma. The two were "blown away" by Burton's use of a wah-wah pedal and asked him to join Metallica. Hetfield and Mustaine wanted McGovney to leave because they thought he "didn't contribute anything, he just followed". Although Burton initially declined the offer, by the end of the year, he had accepted on the condition the band move to El Cerrito in the San Francisco Bay Area. Metallica's first live performance with Burton was at the nightclub The Stone in March 1983, and the first recording to feature Burton was the "Megaforce" demo (1983).
