Outside of his own musical work, he has co-written or produced albums for Mac Miller, Anderson .Paak, The Kid Laroi, Banks, Herbie Hancock, Big K.R.I.T., Brittany Howard, Bilal, Denzel Curry, Q-Tip, and Talib Kweli, among others.

He won the 2017 Primetime Emmy Award for Outstanding Original Music and Lyrics for his song "A Letter to the Free" featured in Ava DuVernay's documentary, 13th, along with Common and Karriem Riggins.

[8] Glasper's playing career was launched in earnest whilst still studying at The New School in New York when he started touring as a sideman with some of the established greats of the scene (bassist Christian McBride, and trumpeters Terence Blanchard and Roy Hargrove).

Primarily a piano trio recording, with Bob Hurst on bass and Damion Reid on drums, the album also features saxophonists Marcus Strickland and John Ellis, along with the vocalist Bilal.

[9] In 2005, Glasper released his debut on Blue Note Records, Canvas, with what was to become his quintessential piano trio lineup of Vicente Archer on bass and Damion Reid on drums.

His third album, In My Element, was released in 2007 and includes songs written in honor of Glasper's mother ("Tribute") and hip hop producer J Dilla ("J Dillalude").

The pianist also revisits Hancock's "Maiden Voyage" in what was becoming his signature fusion style, moving between contemporary and classic as it segues into a version of Radiohead's "Everything in Its Right Place", and quoting Duke Ellington's "Fleurette Africaine".

In February 2012, Glasper released his fifth and seminal album Black Radio, which featured performances by a lineup of neo-soul and hip-hop artists including Lupe Fiasco, Bilal, Lalah Hathaway, Erykah Badu, and Yasiin Bey.

Guest vocalists included Common, Brandy, Jill Scott, Marsha Ambrosius, Anthony Hamilton, Faith Evans, Norah Jones, Snoop Dogg, Lupe Fiasco, and Emeli Sandé.

Notably, Lalah Hathaway and Malcolm-Jamal Warner were featured on a cover of Stevie Wonder's "Jesus Children of America", a dedication to the victims of the Sandy Hook Elementary School shootings.

On June 16, 2015, Robert Glasper released Covered, a return to his acoustic piano trio format alongside musicians Damion Reid and Vicente Archer.

The album features cover songs, drawn from an eclectic variety of artists, including Radiohead, John Legend, Kendrick Lamar, and Joni Mitchell.

The album features artists bringing a contemporary reimagining of Nina Simone's catalogue including contributions from Usher, Common, and Mary J. Blige.

The album includes features from Stevie Wonder, Bilal, Illa J, Erykah Badu, Phonte, Hiatus Kaiyote, Laura Mvula, Georgia Anne Muldrow, Ledisi, and John Scofield.

It features saxophonist and vocalist Casey Benjamin, bassist Derrick Hodge and drummer Mark Colenburg alongside Glasper, and was recorded in New Orleans.

2016 saw Glasper receive attention for his prominent role on Kendrick Lamar's critically acclaimed album To Pimp a Butterfly, notably playing on the Grammy-winning track "These Walls".

In January 2017, Glasper performed with Christina Aguilera at Taking the Stage, the celebratory concert commemorating the opening of the Smithsonian's new National Museum of African American History and Culture in Washington, D.C.

A celebration of African American protest music, the show featured Jill Scott, Bilal, Staceyann Chin, and Toshi Reagon alongside a special big band ensemble led by Glasper.

In 2018 Glasper formed two new supergroups: R+R=Now with Terrace Martin, Derrick Hodge, Taylor McFerrin, Christian Scott, and Justin Tyson;[11] and August Greene with Common and Karriem Riggins accompanied by Burniss Travis and Samora Pinderhughes.

Guests have ranged from Common, Black Thought, Yebba and Q-Tip to Angela Davis and Ilyasah Shabazz, Dave Chappelle and Tiffany Haddish, many of whom have made unscripted appearances performing with Glasper as well as watching the show.

Fuck Yo Feelings is the result of a two-day session in which Glasper texted invitations to his musician friends to stop by the studio and organically create together.

Featured artists, who included Herbie Hancock, Cordae, Buddy, Andra Day, Yebba, Baby Rose and Rapsody, often composed their contributions on the spot.

"[14] With primary influences in neo-soul, hip-hop, jazz, gospel, and R&B, Glasper also has reinterpreted songs from rock acts Nirvana, Radiohead, Soundgarden, and David Bowie.
