He first started out as a deejay under the name of Superman deejaying in combination with Jamaican deejay Spiderman. They recorded their debut album Superman and Spiderman in '84 for Ranking Joe and it was released on Kingdom Records in '85. It was recorded at Harry J's and Channel One in Jamaica. Sandeeno then moved to Kingston in order to be nearer the studios. During the coming years they recorded for various producers and released singles on labels such as Jammy's Records, Shocking Vibes, Penthouse Records, Steely & Clevie Records, Mr. Doo, Soljie and others.
In early 90s they met with Charlie Morgan (2) of Outernational Records and released the album It Ain't Easy in '93 which was critically acclaimed. The duo then toured Europe (Switzerland). After the tour they agreed to dissolve the partnership and Superman changed his name to Sandeeno.
He released his first solo record on the Black Roots imprint "Gangster". In '95 he moved into self-production with the single Ten Commitments showcasing him being able to both deejay and sing. Several singles followed for various producers.
In '96 Sandeeno recorded Teardown Babylon for Mykey Simpson's MCS Records. The song was quite a hit and reached #1 on the english charts and stayed there for several months becoming somewhat of an anthem. Successful singles such as "Nah Go Down Deh" and "Mankind" followed. These and other singles were collected for the '98 album Teardown Babylon.
Since then he has recorded for producers such as Gussie P., Blacker Dread and Fashion Records among others.
In 2008 Sandeeno released the album Guncrime Gone Crazy that was focused entirely on anti-gun and uplifting messages.
