Duality (stylized as DU∆LITY) is the debut mixtape from Captain Murphy, the animated rapper alter-ego of experimental musician Flying Lotus.

[4] 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.

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.

The album features samples from the 1987 film Robocop, also referenced in Flying Lotus' rap name Captain Murphy after the titular Officer Murphy, as well as recordings of Marshall Applewhite of Heaven's gate, Carey Burtt's Mind Control Made Easy, Kenneth Anger's Invocation of my demon brother, Lucifer Rising, and archival documentary recordings.

[6] On the night of the deluxe version release, Murphy played his first show at the Low End Theory in Los Angeles, California.
