The 2015 Hellfest is already in the books, but there's one pretty cool performance that a lot of the festival goers likely missed … unless they somehow found themselves hanging outside the converted bus studio of Comite Des Reprises. An all-star lineup of musicians from the festival took their turns laying down parts for a cover of AC/DC's "Highway to Hell." (Get it, Hellfest ... "Highway to Hell").

Given the space and scheduling limitations, not all of the participants were on hand at the same time, but the cover comes together quite well. Irish rockers The Answer, who have drawn comparisons to AC/DC and shared stages with the rock legends over the years, lead the way with Cormac Neeson delivering the vocals. He's also joined frequently on vocal lead by Soulfly and Cavalera Conspiracy frontman Max Cavalera, who offers a gruffer vocal counterpoint.

Other members of the all-star collective include the entire bands Butcher Babies and Ladies Ballbreaker, plus Korn's Brian "Head" Welch, Five Finger Death Punch's Jason Hook, In Flames' Bjorn Gelotte, Airbourne's Joel O'Keefe, Alice Cooper guitarist Ryan Roxie, Les Wampas' Didier Wampas, Carousel Vertigo's Jansen Press, plus Charlie Parra Del Riego, Steven Andre and Dedo. Check out the cover above.

The 10th Anniversary of Hellfest featured Slipknot, Scorpions, Faith No More, Judas Priest, Korn, ZZ Top, Slash and Motorhead among its top billed acts. In all, over 150,000 people attended this year's music weekend. Hellfest will return for its eleventh year on June 17-19, 2016.
