"Birthday" marks the first time that Disclosure have worked with both Kehlani and Syd, and is the fourth single to be lifted from ENERGY, after Fatoumata Diawara collaboration "Douha (Mali Mali)", slowthai and Aminé collaboration "My High" and the title-track "ENERGY".
Howard Lawrence of the duo says of the song, "Syd & I were going through a similar thing at the time, trying to work out if it was cool to call your ex to say hi or is it too awkward / mean to do so out of the blueI?"
Guy Lawrence adds, "It’s the oldest song on the album by far so has definitely stood the test of time and deservedly made the cut, and the addition of Kehlani just took it to the next level and turned into a fire duet."
ENERGY will be Disclosure's first album in five years, after Caracal, and will feature guest appearances from Mick Jenkins, Common, Channel Tres, Kelis, Kehlani, Syd and more.
The duo say of the album title, "The thing that decided which songs made it and which songs didn’t was that one word: energy. Every track was written really quickly. That’s why we had to write so many songs because those ones don’t come up every day. Or every week. Or every month."
