WATCH: Mark Morton & Mille Petrozza discuss being 'Unified Through Thrash'

Ahead of their tour that's set to savage its way across Europe this spring, Lamb Of God riff master Mark Morton and Kreator vocalist/guitarist Mille Petrozza sat with BBC Radio 1's Daniel Carter to discuss their first exposure to heavy metal.

Though this is merely one of many trailers before the full video is unleashed - it's a fascinating look into which bands specifically captured the two, and how they've gone to be influenced by them since.

On the upcoming State Of Unrest tour, Lamb Of God vocalist Randy Blythe said: "It's always a blast when you tour with someone for the first time, so we're looking forward to hitting the road with Keator, as well as getting some more hang time with our maniac pals in Power Trip. See ya in March and April!"

Mille Petrozza himself added his thoughts on the tour too: "Hordes of Europe! It is my pleasure to introduce the State Of Unrest tour; for too long European and American metal has been divided and now it is time for unity! We are excited to be playing our only European shows of 2020 with the mighty Lamb Of God and support from one of my favorite new thrash bands, Power Trip. It's going to be a wild night of metal celebration - DO NOT MISS OUT!"
