For those who don't know who Jeff Hanneman is, he is one of the founding members of Thrash Metal mega group Slayer. One of the Big Four (Or Founding Four.) of Thrash Metal. Along with Metallica, Megadeth, and Anthrax. Jeff died May 2, 2013 at 11:00 A.M. from Liver failure, and his death has forever changed the music industry. Jeff, and Slayer started out as an Iron Maiden, and Judas Priest cover band. After covering Maiden's famous Phantom of the Opera, at the Woodstock Club in Anaheim, California, the band was asked by former music journalist Brian Slagel to preform the original song Aggressive Perfector for Slagel's  Metal Massacre III compilation. The rest as they say is history, and Slayer became one of the biggest metal bands in human history. Truly this is a sad week for music, and may Jeff rest in peace. As for his band mates, My condolences go out to them, and Jeff's family as well. As a long time Slayer fan, this was a heavy blow, and I hope the band along with Jeff are immortalized in the Rock and Roll Hall of Fame in the near future. R.I.P. Jeff, you where truly one of the greatest guitarist to ever live.
