Quadron

In 2009, Hannibal and Coco O. of electronica collective Boom Clap Bachelors formed the group Quadron.^[3] The name of the band refers to the multi-racial heritage of the band members (from the term "quadroon").^[3] Both Hannibal and Coco O. have one biracial parent.^[3]

Quadron's first professional project, released 2009, was a collection of seven songs on the soundtrack for the Hella Joof movie, Hush Little Baby^[4] including the film's theme song "Slippin'". Their music gained wider prominence in the United States due to Hannibal's connections to US-based music industry professionals. They re-located to Los Angeles in 2010.^[3]

The duo released their eponymous debut album under Plug Research in 2010. Their second album, Avalanche, was released in June 2013.^[3]

In 2011, Quadron contributed the track "Samba De Verão" to the Red Hot Organizations charitable album Red Hot+Rio 2. The album is a follow-up to the 1996 Red Hot + Rio. Proceeds from the sales were donated to raise awareness and money to fight HIV/AIDS and related health and social issues. That year they also collaborated with American DJ and record producer Kaskade for the song "Waste Love" off his album Fire & Ice.

In 2014 Quadron was booked as the opening act on Mayer Hawthorne's U.S. tour.^[5]
