Sir LSG began his career as a DJ in 2006 whilst studying to become an electrical engineer at the University of The Witwaterstrand. It seems the love for music soon took precedence as the young SIr LSG started collecting records. Soon after Co-founding Hood Natives in 2007 with 3 other DJs based in Soweto, Sir LSG enrolled at the Soul Candi Institute of Music to learn more about electronic music production. After completing the short course at Soul Candi, Sir LSG enrolled at the Academy of Sound Engineering to do a two year diploma majoring in Music Production & Audio Post Production.
It was the 2008 Southern African Music Conference that became a defining juncture in Sir LSG's music path, when he caught the ear of legendary DJ Christos, whom since became his mentor. Thanks to the relationship with Christos, German producer Ralf GUM came across Sir LSG's song “Sax in the City” in 2011 , which finally found its way to light when released on GOGO Music. With remixes from another German based Producer Raw Artistic Soul, and a fellow South African DJ/Producer Nastee Nev, "Sax In The City" reached the second spot on Traxsource's top singles chart.
To date, the Mafikeng born Lesego Sefako has collaborated with Brian Temba, a legendary South African R&B singer/songwriter and trumpeter Kafele on a song titled All I Am, which enjoyed great air play on South African Radio Stations and became a local dance floor anthem. In 2014 Sir LSG was voted by Traxsource at Number 20 on the Top 100 Afro House Producers of the year.
