On August 19, 2015, Slipknot played the legendary Red Rocks Ampitheater. Right as the band blasted into their hit "Before I Forget," frontman Corey Taylor invited fans to record the track and send their footage to the band. Slipknot have now released the fan filmed video. The result is a fun video clip, which gave me some acid reflux thinking about how hard it must've been to sync all the different video formats in time.
Slipknot will begin writing new material later this year, but don't expect any new music for a few years.
