In April, Coachella headliners Phoenix were joined onstage by a surprise guest: Pitchfork Festival headliner R. Kelly. The two parties collab’ed on a pair of great mashups — “1901”/”Ignition” and “Chloroform”/”I’m A Flirt” — and then walked off stage saying, “We gotta do something else!” I’m not paraphrasing or assuming anything; that’s a direct quote from Kelly, as captured in a new video teasing the unlikely pairing’s next project: a Kelly remix of “Trying To Be Cool,” from Phoenix’s last album, Bankrupt! The preview provides just enough music from the remix to be utterly tantalizing. Watch for yourself.
