Flume has finally linked up with London Grammar for a song.

The Australian producer and the U.K. outfit have long been friends and wanted to collaborate, but it hadn't come together until now, with the release of "Let You Know," which is out today via Future Classic.

“[London Grammar vocalist] Hannah Reid and I wrote ‘Let You Know’ last summer,” says Flume of the new song. “I was on a writing trip to London, was actually the same trip where I first met slowthai. Had been wanting to make something with Hannah for a long time and this one just came together really naturally in the studio that day.”

For her part, Reid says: “We’ve been trying to work together for years but it just never worked out with our schedules but I’m so glad it finally did. Working with Harley was an honor because he pushes the boundaries of electronic music like nobody else. He’s the kind of electronic artist who will be around forever. I love our song we did together.”
