TRZTN is the solo project of Tristan Bechet, who was part of Karen O And The Kids over a decade ago. Today (19 January) the two musicians have reunited on a track called "Hieroglyphs", which is accompanied by a video directed by Barnaby Roper.

"Hieroglyphs" marks Karen O's first collaboration since uniting with Willie Nelson in October last year to cover Queen and David Bowie's "Under Pressure".

TRZRN's "Hieroglyphs" single featuring Karen O is out now. His Royal Dagger Ballet album arrives on Friday (22 January).
