Tyga enjoyed worked with Dijon. In 2011, he invited DJ Mustard to produce his single “Rack City” from the LP Careless World: Rise of the Last King. Partially thanks to Dijon’s effort, the song climbed to the 7th spot of Billboard Hot 100, topped R&B/Hip-Hop Songs Chart, and came in second on Hot Rap Songs Chart. It was an overwhelming success for both the rapper and the producer.
In 2012, the producer worked on 2 Chainz’ “I’m Different”. It was worth the effort. The song reached the 6th spot of Hot R&B/Hip-Hop Songs and sold 500 000 digital copies. Later that year, DJ Mustard worked with Young Jeezy to help him promote the song “R.I.P” from mixtape It's Tha World. The same year, DJ Mustard worked with Bow Wow. He helped the rapper release “We In Da Club” from the LP Underrated.
In June 2013, Dijon’s fans finally saw his first mixtape, which had an interesting name, Ketchup, especially considering the artist’s pseudonym. The album was recorded together with YG, Ty$, Nipsey Hussle, Clyde Carson, Joe Moses, Dorrough, Kid Ink, Ca$h Out, Dom Kennedy, Lil Snupe, Casey Veggies, and Lil Jon. Back then, Dijon didn’t work with labels yet so the album was self-released. That didn’t stop many organizers from trying to book DJ Mustard for private events.
Part of 2013, the musician spent on production projects. He worked with HeadBand on B.o.B and with 2 Chaniz on Underground Luxury. With his help, Kid Ink released “Show Me”, which topped U.S. Rhythmic Billboard Chart. In November, the artist announced his plans to release an album with Jay-Z’s label Roc Nation.
