Croker has released seven studio albums — Fundamentals (2006), In the Tradition (2009), Afro Physicist (2014), Escape Velocity (2016), Star People Nation (2019), BLK2Life / A Future Past (2021) and Love Quantum (2022).

Finally, in 2014 Bridgewater produced his third studio album Afro Physicist with him, which featured herself as vocalist on three tracks, guest appearances by vibraphonist Stefon Harris on an interpretation of Stevie Wonder's "Visions", and fellow trumpeter Roy Hargrove surprisingly sings on a composition of his own that Croker then arranged.

In 2013, Croker returned to the United States after a seven-year stay in Shanghai, China, where he broadened his concept of jazz to encompass other genres such as salsa, fusion-rock, R&B, hip-hop and blues.

On March 1, the first single off Star People Nation was released, which paid homage to the jazz musician Elvin Jones, titled "The Messenger" featuring guest pianist ELEW.

A music review by Floriane Esnault from Qwest TV stated, contrary to the political accents that are perhaps contained within the title Star People Nation, Croker refused to enter into this easy "hype" that he sees many musicians devoting themselves to according to.
