As one half of the duo Agnelli & Nelson, Robbie Nelson's DJing career took a gigantic leap forward with the massive success of the duo's first single, "El Niño." This summer 1998 anthem may have made Nelson a superstar, but his career actually began in the early '80s, first peaking with his win at the 1986 DMC Irish Mixing Championship and repeating for the next three years. He has held residencies at many of Ireland's top clubs such as Circus Circus and the Met, in addition to touring as a member of Gatecrasher's 2000 world tour. ~ Jason Birchmeier
