Duality (stylized as Du∆lity), is the debut mixtape from Captain Murphy, the animatedrapperalter-ego of experimental musician Flying Lotus. Initially released as a 34-minute short film featuring songs performed by Murphy as well as archived cult footage (including footage involving Heaven's Gate co-founder Marshall Applewhite), pornography, cartoons and 1980s films. A deluxe edition was released for download on November 28, 2012 with tracks separated, as well as bonus tracks and instrumentals.
Captain Murphy first appeared over the summer of 2012 on the Flying Lotus-produced track "Between Friends" for the 2012 Adult Swim Singles Program. The track also featured Odd Future's Earl Sweatshirt trading verses with Murphy. Speculation began to arise that Murphy was either Tyler, The Creator, Earl Sweatshirt, Flying Lotus, or a combination of the three due to the frequent pitch shifts in vocals. Between July and September 2012, Murphy released several music videos on YouTube that featured animation by lilfuchs. Over the months, Captain Murphy began hinting towards his debut project Duality, which was scheduled to be released in November 2012.
On November 15, 2012, Captain Murphy started a website and posted a 34-minute video titled "Duality" that featured his music as well as archived cult footage and lilfuchs-produced animation. He then began hinting at a deluxe version with separated tracks, bonus tracks and instrumentals. On November 28, Murphy released the deluxe version for download, along with the launch of a merch line. The mixtape was released with separate artwork for each track, created by lilfuchs.
On the night of the deluxe version release, Murphy played his first show at the Low End Theory in Los Angeles, California. He performed his set in a cloak to conceal his identity, but towards the end of the show, he revealed himself to be Flying Lotus.
