Enigmatic producer Sophie has been responsible for some of the most interesting dance music from the past few years — most recently the one-two punch of “Lemonade“/”Hard” — but he’s been wrapped up in a lot of mystery and the release of new music has been frustratingly sporadic. It seems like that trend will continue: At a Boiler Room set this past Friday, the producer DJ’d as one-half of QT — a duo with PC Music leader A. G. Cook — and apparently sent out a drag queen to act as his stand-in. During the set, they debuted a new song called “Hey QT,” which we’ve only heard a snippet from previously. You can stream part of their set below — “Hey QT” comes in at 4:40.

A release from QT is forthcoming on XL Recordings.
