While in high school, he produced his first record with reggae instrumentalist Augustus Pablo and vocalist Lee "Scratch" Perry.
He was in fact King Tubby's first trainee, recording and mixing such hits as "None Shall Escape" by Johnny Clarke, "Jah Love" by Yabby U, and most of Dr. Alimantado's albums.
The first recording project was with the group Monyaka, titled "Go Deh Yaka", which was an instant hit, and reached number 14 on the UK Singles Chart.
[2] Later that year, Shaggy recorded "Mampie" with Smart;[2] Red Fox and Screechie Dan's "Pose Off"; and "Shot Mek You Wiggle" by Junior Demus, which was later used in the film "Dancehall Queen".
Smart's early Pro Tools and analog technology knowledge gave him a cutting edge in the 1990s, which provided reggae artists with the ability to record Jamaican-quality sound in New York.
