London on da Track

In August 2014, American rapper and Cash Money Records chief executive officer (CEO) Bryan "Birdman" Williams, called London "the best producer in the business, as we speak today". London's frequent collaborator, Atlanta-based rapper Young Thug has stated London is his favorite producer to work with and will go down as "the greatest producer ever". Complex included him on their 2013 list of "25 New Producers To Watch For". In August 2014, three singles, produced by London on da Track, charted on the Billboard Hot 100 at the same time, with "Lifestyle" at 16, "About the Money" at 42, and "Hookah" at 85. In 2018, he appeared in Black Ink Crew: Chicago. That same year, he was named to Spotify's Secret Genius Ambassador's list. In 2019, he appeared in Netflix's Rhythm + Flow, as a producer advisor in the finale.

London began rapping at the age of sixteen with the group Dem Guyz. The group used to download beats on SoundClick for 99 cents, although most of the beats cost $100 for exclusive rights. As a way to save money, London drew upon his experience playing piano arrangements in church and began making beats for rappers. With the help of online software he was able to refine his craft. He gained local acclaim when he began producing beats for the Rich Kidz . Soon after, others began asking for his compositions. Early on in his career, London would give away his beats for free as a means to build connections and garner more publicity. The first song he produced that received radio play was "Pieon" by Rich Kidz. The success of "Pieon" motivated London to continue producing. In 2011, he recorded his first of many collaborations with Young Thug, "Curtains." London continued to give his beats away for free before signing his first label deal with Cash Money Records.
