No Need for Alarm saw the introduction of the Oakland clique Hieroglyphics,[2] whose original members included Souls of Mischief (Opio, A-Plus, Phesto and Tajai), Casual, Pep Love, Del, and producer Domino.

About a month before the release of his third album, Future Development, Del received a letter from his label, Elektra, stating that his contract had been terminated.

Two years later, Del released his fourth solo album, Both Sides of the Brain, as well as Deltron 3030 which was a collaborative work with artists Dan the Automator and Kid Koala.

Del released the album Golden Era on April 19, 2011, in a three-disc set including Funk Man (The Stimulus Package) and Automatik Statik.

"Press Rewind" was the song for Eero Ettala's part in the film White Balance and "If You Must" was featured in DC Mountain Lab.

Del collaborated with John King of the Dust Brothers and Mark Mothersbaugh of Devo to produce the original score for Skate 3, released in May 2010.

He made a guest appearance as a rapper named "Old Skool" (paying homage to Del's prominence in the 1990s) on the Nickelodeon series Middlemost Post on the episode "The Same Ol' Same".

Exposure from the 3030 project helped to expand Del's fan base—the 3030 project worked well as a marketing move because the CD capitalized on the growing interest of computer technology, incorporating motifs of science fiction, telling stories about life and hip hop based in the year 3030, and infusing much of the popular internet terminology and culture in circulation at the time.

Del collaborated with the virtual band Gorillaz on two songs on their debut album, "Clint Eastwood" and "Rock the House", both of which became singles and videos and achieved chart success.

By the time Del came onto the project, the album was already finished, and British hip-hop group Phi Life Cypher had already recorded verses for "Clint Eastwood".

In March 2010, Del collaborated with independent pop/funk duo Modern Science on a track called "Do It Right Now" that is available on the band's Bandcamp website.

In September 2013, Del appeared on two tracks from Figure's Horns of the Apocalypse EP: "Beast Mode" and "War Call".

In April 2017, Del appeared (along with Carnage the Executor) on the track "Lone Wolves" from Cas One Vs Figure's "So Our Egos Don't Kill Us".

In 2017, Del was a guest artist on the debut album of Halo Orbit (a band featuring Juan Alderete, ex–Mars Volta and Mark Guiliana) on the track "One Of These Days".

[14] On July 7, 2018, as he was appearing with Gorillaz during the final act of the 2018 Roskilde Festival, Del fell off the stage during a performance of "Clint Eastwood".

[16] Del once again collaborated with Gorillaz in 2023, appearing on the Cracker Island deluxe edition bonus track "Captain Chicken".
