Cristalle Bowen, also known as Psalm One, has been consistently named one of the nation's Best Artists by the Chicago Tribune, and in 2011 made her television debut on MTV's Emmy-winning series, MADE.  She is an international touring and recording artist; featured in publications such as Vice, Forbes, and The FADER. An artist cut from Chicago's vast and unique HipHop talent, Psalm has commanded stages of festivals from Paid Due$ to Riot Fest; among artists such as Kendrick Lamar, 50 Cent, Jean Grae, Odd Future, Wu - Tang and so many more... Not just an MC, Psalm has also been road DJ for rap legends. More than an entertainer, Cristalle is also an activist, scholar and teaching artist.

Cristalle released her debut album, Bio:Chemistry, while studying chemistry at the University of Illinois in 2002; was discovered by Casual of Hieroglyphics fame and brought to Rhymesayers Entertainment by Eyedea (RIP). In 2006 Psalm One became the only woman signed to the independent label after leaving her job as a chemist and releasing her commercial debut, The Death of Frequent Flyer. In 2013, she began releasing music under the pseudonym Hologram Kizzie, while co-founding the crew Rapperchicks. In 2015,  she challenged Rhymesayers' practices toward women, herself then being the only woman signed to the imprint in its 20+ year history.

Not just a professional-turned-performer, Cristalle has always utilized her platform in many unique ways, not the least of which is educational. In 2012 she released a children's album, titled Child Support in conjunction with ASCAP and America SCORES, a nationally celebrated after-school program; she regularly balanced time between touring and running the hip-hop influenced after-school program Rhymeschool; as an advocate of equal rights across the board, Psalm One frequently speaks on panels and conducts workshops in the academic sphere.

In 2015 she self-released P.O.L.Y. (Psalm One Loves You), and embarked on a U.S. tour she orchestrated herself. P.O.L.Y. broke new ground for Psalm One, as it shows a beautiful amount of live instrumentation and group vocals. Fittingly, the album was named  one of the year’s best by multiple publications. 2015 also marked the Rapperchicks' debut, Shitty Punk Album, as well as the release of Psalm’s incredible triple album Gender Fender Bender. 

In 2020, the Rapperchicks became BIG $ILKY, a duo between herself and long time collaborator Angel Davanport. The two released two music projects and launched a web series during the pandemic, to much acclaim. They’ve also pivoted to mutual aid and Covid-19 relief, with Angel forming the S.H.I.F.T. Cooperative and Psalm joining the board. They’ve redistributed tens of thousands of dollars to Midwest families in need. 2022 is shaping up to be even bigger, with more mutual aid, music and Psalm One’s first book out now. She is not slowing down and more independent than ever before!
