He initially met Burkle through at a Grammy party and helped him invest in Spotify.

In 2013, D.A. began writing and recording music as a solo artist. He played his music for Odd Future and Frank Ocean manager Chris Clancy, who then partnered with Harvest Records to release D.A.'s solo project. He released his first single, entitled Glowing, in October 2013, which debuted in a music video directed by Tyler, The Creator. The video was originally released "anonymously" before Wallach came out as the singer of the song in an interview with MTV, who called it a "Beatles-esque love song." When asked why he released the video anonymously, D.A. stated that he just wanted people to enjoy the song. D.A. followed up with his second solo release, Farm, in November 2013.

D.A. appeared in the 2012 film Artifact produced by Jared Leto.

Outside of Chester French, D.A. has worked with Supa Dups, forming the group D.A. & the Supa Dups. They collaborated in 2011 and released 2 singles, Who Do You Know and Too Cool (feat. Vybz Kartel).

In 2011, D.A. was selected by Sean Parker, Shakil Khan, and Daniel Ek to be the official artist-in-residence for Spotify. In that capacity, he created and led the Artist Services team, which oversaw the company's relationships with musicians and managers, discussing how the service works, its payment model, and promotions. He has also driven different products for the company including its Artist Analytics dashboard and its merchandise and ticketing products. D.A. has advocated publicly for subscription music services to be embraced by both artists and the music industry. Spotify's subscribers grew from one million to 20 million prior to him leaving the company in 2015.

D.A. went on to attend Harvard University. During his time at Harvard, he studied African-American studies under Henry Louis Gates Jr. and graduated in 2007, receiving both the Alain Locke Prize for the most outstanding scholar in African-American Studies and the Andrew Ramroop prize. He received Harvard's first certificate in the Bantu language Gikuyu.

D.A. worked as a recording engineer in Harvard's student recording studio, engineering and producing for Boston-area jazz musicians and working on Chester French's debut album at night. In 2007, D.A. sent out hundreds of demo CDs which led to a bidding war between West, Dupri, and Williams. Just prior to D.A.'s graduating from Harvard, Williams signed the group to his Star Trak Entertainment label, a partnership with Interscope Records. The group was known for being one of the first bands to use Facebook as a promotional tool to interact with fans being freshmen at Harvard the same year that the site was launched by Mark Zuckerberg. D.A. was also an early adopter of Twitter with over one million followers. During his time with Chester French, D.A. toured with bands such as N*E*R*D, Blink 182, and Weezer. The group's first album included the single She Loves Everybody which reached #1 on U.S. Billboard Hot Dance Singles Sales and #2 on U.S. Billboard Hot Singles Sales.
