Deluxe box including four vinyl LPs, five CDs, A DVD, 64 page book, a Metallica patch and more. Digitally remastered edition of Metallica's 1983 debut album. Kill 'Em All is regarded as a groundbreaking album for thrash metal because of its precise musicianship, which fuses New Wave of British Heavy Metal riffs with hardcore punk tempos. Its musical approach and lyrics were markedly different from rock's mainstream of the early ‘80s and inspired a number of bands who followed in similar manner. Metallica is easily one of the best, most influential heavy metal band of the '80s. Responsible for bringing the genre back to Earth, the bandmates looked and talked like they were from the street, shunning the usual rockstar games of metal musicians during the early '80s. They expanded the limits of thrash, using speed and volume not for their own sake, but to enhance their intricately structured compositions.
