In 2007, Teenage Bad Girl released "Cocotte", on Citizen (Vitalic's label, but not only), a record combining the punk energy of the two boys' beginnings (in rock groups), the broken rhythms of barren hip-hop and the dancefloor efficiency of half French-touch (first school), half Detroit oldschool techno. Result ? The press panics, the public follows by piling on the dance floor to their uninhibited beats and their devastating tracks are playlisted by Chloé, Justice, Erol Alkan, Digitalism, Mylo, John Lord Fonda, Boys Noize, Yuksek, Dj Hell... In 2011 they released their second album “Backwash” more pop and sung than "Cocotte", and carried by the vocoded voice of Greg and the featurings of Rye Rye, Todd Fink and Illa J. We find there the techno efficiency of the beginnings, the taste for tinkering of all kinds (which sometimes evokes Aphex Twin) but easier to access. After a long period of silence Greg and Guillaume had the strong desire to get together to create music again. If the first two albums were entirely produced remotely by exchanging audio files, for this third opus, the French electro duo found themselves in the studio for several weeks. Greg and Guillaume wrote and composed together and side by side the 13 titles of “Separate”. Each track transcribes the spontaneity felt by the group during these sessions. There we find electronic sounds which give pride of place to disco funk, tinged with modernity and pop melodies flirting with the eighties.
