After listening to music by Jimi Hendrix, Harvey joined the Toronto funk and soul band Crack of Dawn, which was signed by Columbia Records and had hits in Canada with "It's Alright" and "Keep the Faith" in 1976.

[3] In the mid-1970s, Harvey visited Jamaica regularly and recorded as a member of Bunny Lee's house band The Aggrovators,[4] playing on albums such as Kaya Dub, Jackie Mittoo's In Cold Blood and King in the Arena, and also played guitar on Willi Williams' Messenger Man.

The album was given a wider release, with correct title and credits, in 2005 by Makasound Records.

In the 1980s, Harvey became the lead guitarist of Toots & the Maytals, and has been with the band for over twenty-five years.

[8][9] Harvey also toured with his own band, with Jackie Mittoo, and worked as a record producer, producing four albums by Messenjah (two of which were nominated for Juno Awards), and recordings by the Juno-winning Kim Richardson and Sway.
