"In these next months I hope to honor the tradition of Star Wars' musical landscape while propelling The Mandalorian into new and unchartered territory," Göransson said. "And I will try to remember that there is no try."
The Mandalorian, produced by Jon Favreau, stars Pedro Pascal of Game of Thrones as a lone Mandalorian gunfighter, alongside Gina Carano, Giancarlo Esposito, Emily Swallow, Carl Weathers, Omid Abtahi, Werner Herzog and Nick Nolte.
The new Star Wars series will be exclusive to the direct-to-consumer streaming service Disney+, which is set to launch in the US in late 2019.
