Dark Time Sunshine is comprised of Onry Ozzborn of Grayskul (Rhymesayers) and producer Zavala. Onry and Zavala first met and collaborated while working on mutual friend and rap artist Sleep's 'Hesitation Wounds' in 2009 (Strange Famous). After this session the two continued their collaborative efforts and began amassing a collection of songs, melding Onry's debonair persona and wordplay with Zavala's strikingly innovative production to create Dark Time Sunshine's signature sound.

The first song completed, "Mod Volatile", appears on Grayskul's 7" released by Fieldwerk Recordings in June 2009. The new partnership culminated in December 2009 with Dark Time Sunshine's 'Believeyoume, a nine song EP, released as a free download and limited CD from Fake Four Inc. In April 2010 Dark Time Sunshine released their first full-length LP, the acclaimed 'Vessel' (Fake Four Inc.).

With two superb releases and extensive touring in the U.S. with the likes of Sole and the Skyrider Band, AWOL One, Pigeon John, and DJ Abilities, Dark Time Sunshine quickly became an indie favorite and 'Vessel' became one of the most well received hip hop albums of 2010. Dark Time Sunshine's performance at Soundset 2010, one of indie hip hop's most celebrated festivals, continued to increase their fanbase and expose new listeners to 'Vessel', often referred to as "psychedelic Gang Starr". Dark Time Sunshine released 'Cornucopia', an EP of unreleased material, for their Fall 2010 "Make A Darwish" tour. In October 2010, Zavala was named to URB's 10 Awesome New Beat Makers.
