As he worked on honing his sound – a seductive blend of progressive house tinged with electro and acid – he sent a bootleg of David Guetta smash When Love Takes Over out into the world. The track’s online success piqued the interest of Guetta himself and in that moment Romero found his mentor and champion. They have since collaborated on multiple projects including Metropolis and Wild One Two, and in the summer of 2012 Nicky Romero accepted a residency at David Guetta’s infamous FMIF club night at Pacha/Ushuaia Ibiza.
