Electric Guest are an indie-pop pop band fronted by Asa Taccone, brother to Jorma Taccone of the Lonely Island. They tapped Danger Mouse to produce their 2012 debut Mondo, and now they’ve enlisted Haim to provide backup vocals on “Dear To Me,” their first song in nearly five years and the first single from their upcoming sophomore LP. Here’s what Taccone told The Fader about the track:

This is possibly my favorite song from our new album. It came from the heart. Matthew (my bandmate) had a job at this studio in LA that had all of these old synthesizers from the 70s and 80s lying around. I came in one afternoon for just a few hours and we played around with as many of the instruments as we could, then recorded most of the rest of the song in my bedroom. One of the Haim girls lives down the street from me, so one day all three sisters came over with some other friends of mine and after hanging out for a few hours we went into my little studio and recorded the chorus vocals. I recorded them on one mic. It’s easy with them because they’re been singing together for years so they blend super well.

The song is a sleek yet soulful synthpop slow-jam, and you can hear it below.

Electric Guest’s new album will be out early next year.
