The mid-1990s were boom times for British music, the high watermark of Britpop. Or, as Epworth says with a grin, ‘the Kill Your Friends era’, referring to John Niven’s best-selling (and soon to be filmed) novel about the drug-crazed record industry. ‘Those were funny days,’ he acknowledges. Making albums when artists were high on cocaine was no way to secure high fidelity. ‘Yeah! Everything has way too much treble on it! I worked on an Oasis record, so I can vouch for that.’ That record was 1997’s Be Here Now, the follow-up to (What’s The Story) Morning Glory?, an album that was infamously recorded in a blizzard of coke. ‘That was hilarious. It was a case of everything being as loud as everything else.’ He did re-mixes for Shaznay Lewis and The Futureheads and soon became the go-to producer for a clutch of sharp young British guitar groups, including Maxïmo Park, Bloc Party and The Rakes. His work with the last two bands snared Mercury Music Prize nominations. He earned his first writing credits on Kate Nash’s number one album Made of Bricks (for which he was nominated for an Ivor Novello award), worked with Plan B on both his albums, and, in 2009, earned two more Mercury nominations for Florence’s Lungs and Friendly Fires’ self-titled debut. Epworth had lift-off.
