Paul Epworth is behind some of the biggest pop records of the last 20 years, from Adele's Rolling in the Deep to Florence and the Machine's Rabbit Heart (Raise It Up).
Along the way he's worked with Rihanna, Stormzy, Sir Paul McCartney, Coldplay and U2 - and he won an Oscar for co-writing the Bond theme Skyfall.
But now, after years behind the scenes, the producer is releasing his first solo album. Voyager, a journey into deep space, fuses influences from classic sci-fi movies with his love of musical explorers like David Bowie, George Clinton, Wendy Carlos and Jean-Michel Jarre.
"It's a sort of '70s space concept album, which is a bit of a cliché as a producer - to make something that ostentatious and overblown," he told BBC News.
"But I've tried to frame it in a modern way, so I've got some great singers and rappers on it."
