S² aka Santiago Salazar started dj'ing in 1992. Being sparked by mix tapes his brother was bringing back from the Gay underground scene in Los Angeles. Santiago got his first break at a afterhours club called 'The Beverly Room' dj'ing from Midnight til' 5:00am. He soon became an underground favorite of the Gay house scene. Later, he got gigs at other afterhour clubs such as 'Respect', 'Graveyard Shift' and 'Reactor.' Having played with L.A. legends such as Chris Flores, Andrew D., Edgar C., DJ Lee and Tony Powell, he credits them for helping to define his style of mixing.

Santiago has mixed and edited several UR 12 inches and was the featured Los Hermanos remixer on "Return Of The Dragons", an exceptional remix that was played by everyone from Ben Sims to Pete Tong! Santiago was also responsible for the limited 7 inch remix of DJ Rolando's "Aguila". He recently released the "Slide EP" under the name Seldom Seen, an experiment in acid-funk and creative sampling, adding a new direction to the classic UR catalog.

He's now a core member of the Galaxy 2 Galaxy and Los Hermanos live bands, using his DJ skills to control the flow and intensity of the live performances.
