Since the 2003 split, Greaves has worked with former Watchmen bandmate Ken Tizzard in the duo Audio Playground High + Wide.
Tizzard and Greaves performed in a series of live visual music presentations at venues such as Ted's Wrecking Yard and the Berkley Church.
[citation needed] After leaving The Watchmen, Greaves founded the band Doctor with bassist Rob Higgins, a former member of Change of Heart.
In 2005, Greaves contributed vocals to the track "This Longing" on the Neverending White Lights debut CD Act 1: Goodbye Friends of the Heavenly Bodies.
In 2006, he contributed to Winnipeg producer Darcy Ataman's new tune "A Song for Africa" which was a benefit project to raise funds for African AIDS relief.
Greaves rarely spoke about his racial identity during the height of the Watchmen's career; however, in 2020, amid the global reckoning around racism that followed the murder of George Floyd, he wrote a first-person essay for CBC Radio reflecting on how his upbringing as the son of a Black Canadian father and a Jewish mother had shaped him.
