Daisy Jones And The Six songwriter Marcus Mumford: The cast sounds so good it "kinda pisses me off"
Marcus Mumford, who helped write Daisy Jones And The Six's biggest hit, praises Sam Claflin and Riley Keough for their singing

If there’s one takeaway from the Daisy Jones And The Six press tour, it’s that 1) the leads didn’t know how to sing or play instruments when they were cast, and 2) they learned how and actually became so adept that they sounded like actual rock stars. You can judge for yourself by listening to the fictional band’s real album, or tuning into the series on Prime Video. Or you can take Marcus Mumford’s word on it.
Aurora producer Blake Mills’ many songwriting collaborators on the album included Mumford, who wanted to help his friend’s “epic quest” to create a period-appropriate but wholly original body of work for the series. The Grammy winner is a co-writer on “Look At Us Now (Honeycomb),” one of the album’s best tracks and the band’s first big breakout hit.
