R.I.P. Jeff Hanneman, one of the greatest guitarists in metal history, and true pioneer of thrash metal. Without Jeff, Slayer wouldn't have created some of the most famous riffs in metal. Hanneman wrote music for the band's hits such as: "Angel of Death", "Seasons in the Abyss" and of course, "Raining Blood". Labelled by Corey Taylor of Slipknot as: 'one of the most underrated writers and players there ever was', and by Slash of Guns n' Roses as: 'the king of thrash/speed metal', no one would influence a genre quite like he did.
