The first blow ...

Show No Mercy was the first blow of Slayer, 4 more classics were to follow before it was somewhat weaker.
On the SNM NWoBHM pay homage, in its most beautiful form. Recalls part of Venom and Motorhead, largely but kept extremely to Iron Maiden, which is mainly reflected by the brilliant solos of lords and King Hanneman (see Crionics). The album looks natural yet somewhat immature, but you have to remember that it was the first album of the band, also everyone has the still more ingenious successor in mind. In 1983 this album, however, was a thunderclap and Slayer were suddenly metal band. 22 years after the disc has lost none of its magic, definitely one of the best debuts of a band ever (along with Metallica and Exodus)
