Today, June 6th, is the International Day Of Slayer, the annual heavy-metal holiday that celebrates the uncompromising, loud and defiant music of the iconic band.

From Tom Araya, Kerry King, Paul Bostaph and Gary Holt:

"Thanks to the fans for celebrating this day with us for the past 12 years... keep it going!"

"And, Slayer would also like to thank Jeff Tandy who, 12 years ago, on 6/6/06, launched the National Day Of Slayer site. It grew so big, it became the International Day Of Slayer. Jeff built the site and maintains it to this day. Thanks, Jeff!"
