By the way, they claim Lorde snuck that milkshake photo.

Disclosure’s song with Lorde has that “extra ten percent.”

Earlier this summer, Lorde posted a photo of her and brothers Howard & Guy Lawrence from Disclosure grabbing milkshakes, immediately igniting the rumor mill the trio had a collaboration in the works. Turns out to be true – they made a track together titled “Magnets” for their album Caracal out Sept. 25.

“I’m really excited for her fan base to hear it as well as ours because it’s a really big collab,” they tell Spin, “not just like in terms of her singing on a Disclosure tune but the whole thing is a collab, from the drum sounds to the chords. She was involved with every aspect of the song as opposed to just doing the lyrics and melodies and then leaving the rest to us.”

“It was like someone challenging us, someone saying, ‘We can get that extra ten percent.’ We totally did. ‘Magnets’ was a really nicely written song. The best thing about it is its simplicity. It’s just a load of tribal drums. It’s the shortest song we’ve ever made as Disclosure as well.”
