Quadron is an avant R&B (with an occasional nudge toward folk-soul) duo of multi-instrumentalist/producer Robin Braun – aka Robin Hannibal, also one-half of the duo Owusu & Hannibal and vocalist Coco O.

Previously Coco O. has sung backup for Danish soul artist Karen, and Robin has been collaborating with Nobody Beats The Beats, and Danish rappers Clemens, Jokeren & L.O.C.

Braun and Coco were subsequently sought out by numerous artists – including Leon Ware from The Internet, and Tyler, The Creator – for collaborations.
