When you have a legendary band like Slayer it is pretty cool to see them cover a song from a band like Exodus.

Last night Slayer threw down at the Rockstar Energy Drink Mayhem Festival and performed the Exodus classic "Strike Of The Beast" for the first time ever.

Slayer guitarist Jeff Hanneman has been recovering from necrotising fasciitis, which he got from a spider bite. And Exodus guitarist Gary Holt has been filling in for Jeff while he recovers.

Check out the video of Slayer covering Exodus's "Strike Of The Beast."
