WATCH: Greta Van Fleet's live performance on Jimmy Fallon is so bloody good they got a standing ovation

Fresh off the release of their first single 'When The Curtain Falls', for their forthcoming debut record, Greta Van Fleet took on the silver screen earlier this week. 

The young rockers performed their stonking new tune live on The Tonight Show Starring Jimmy Fallon and transported the audience to an era when old school rock ruled the world.

No surprises, the boys absolutely smashed it out the park, to the point they scored a standing ovation. 

Watch the performance above.
