4. Killing Is My Business... And Business Is Good
Recommended Track: Rattlehead, Mustaine's call to arms and one of Thrash Metal's most enduring anthems. Killing is my Business is undoubtedly Megadeth at their most raw and unrefined and yet the importance of this record to the Thrash genre cannot be underestimated. This is intense thrash metal played at break-neck speed back when the genre was still struggling to find its feet. Lacking the precision of later releases, any holes in composition or playing are filled with boundless energy and pure unbridled passion. Dave Mustaine snarls and barks with the fury of someone with much to prove, his eyes set firmly on usurping Metallica as the number 1 Bay Area Thrash Metal band. He needn't have worried, on the strength of this debut no one doubted him for a second!
