Dijon Isaiah McFarlane  aka as Mustard (formerly DJ Mustard), is an American record producer, DJ, record executive and hype man from Los Angeles, California. He is a frequent collaborator of Compton-bred rapper YG, and has produced numerous singles for hip hop and R&B artists since his entrance into mainstream music in 2011. Mustard's production style has been described as an up-tempo, club oriented, catchy yet rudimentary melodic hip hop style. This style has snowballed into the contemporary production style of West Coast hip hop during the early 2010s, which he calls "ratchet music". Almost all of his productions begin or end with the tag "Mustard on the beat, hoe!", a voice sample of YG, who says it at the end of "I'm Good", one of their early collaborations, as well as claps and repetition of the word "hey". Mustard's debut album, 10 Summers, was released on August 26, 2014.

Mustard was born in California to Jamaican parents. In a 2013 interview with The Fader magazine, he stated that his father was deported to Jamaica when he was at a young age, however, they keep in touch. When Mustard was 11 years old, his uncle, who was both a parental figure and a DJ, let him DJ at a family party. He acquired his DJ name from the condiment dijon mustard because his first name is also Dijon. He began DJing more as he got older, and became much more skilled at the craft which led to him DJing at the local clubs.  Source.
