"I saw Tinariwen by accident at the Cambridge Folk Festival some time in my early 20s. I had a massive hangover, so went to sit in the artists' bit at Cambridge, this bit on the side of the stage where you can see the bands play. I wasn't really paying attention to start with – it was a bad hangover– but slowly but surely this amazing this happened. I was draw in, then hooked in, then totally hypnotised by this music that crashed over me in my little fog. The music had so much forward momentum, and the guitars had so much space, it was like I was being taken off somewhere. It was the most transcendental experience. I love the textural stuff on this record especially – the different types of percussion, the clapping, the chorus singing. The whole thing ebbs and flows.

"Yes, that's the one. I know both recordings, and the movie too, but I think the one I listened to mostly was the later one. In a lot of ways Kurt Weill and Lotte Lenya, and this piece in particular, represent what I'd ultimately like to do as an artist: bringing opera together with popular music; classical singing with everyday life. I've written a couple of operas, I've worked with Shakespeare's sonnets, I've made pop records, and I have this folk background, and I feel that Kurt Weill with The Threepenny Opera was the pinnacle where all of the elements that he was influenced by joined together to create this other animal. Lotte Lenya was the one who interpreted that. It's a really good touchstone to keep in mind in terms of what I do in the pop world and the theatre world."

"I played British and Irish folk in an early band I had. We only performed one show and Rostam [Batmanglij, Vampire Weekend multi-instrumentalist] was also in the group, so this was the roots of Vampire Weekend. We covered 'Matty Groves' from this album. It's a traditional song about adultery, anger and sex, and I thought it was cool that they could take ancient-sounding stories and make them relevant. It's an important lesson – if you want to reinvent the wheel, maybe pop music isn't for you. As much as it's about being progressive, it's also rooted in a certain respect for the form. Which might seem paradoxical, but that's what pop music is – it combines very old ideas with very new sounds. Fairport are an example of that, taking very old songs in the English language and reinventing them."
