Metallica promoted the album on the two-month co-headlining Kill 'Em All for One tour with English heavy metal band Raven in the US. The album also generated two singles: "Whiplash" and "Jump in the Fire". Although the initial shipment was 15,000 copies in the US, the album sold 60,000 copies worldwide by the end of Metallica's Seven Dates of Hell European tour in 1984. The album did not enter the "Billboard" 200 until 1986, when it peaked at number 155, following Metallica's commercial success with its third studio album, "Master of Puppets"; the 1988 Elektra reissue peaked at number 120. "Kill 'Em All" was critically praised at the time of its release and has since been regarded as a groundbreaking album for thrash metal, because of its "precise musicianship, which fused new wave of British heavy metal riffs with hardcore punk tempos". It was also retrospectively placed on a few publications' best album lists. The album's musical approach and lyrics were markedly different from rock's mainstream of the early 1980s and inspired a number of bands who followed in similar manner. It was certified 3× Platinum by the Recording Industry Association of America (RIAA) in 1999 for shipping three million copies in the United States.
