Born in Rome, Leo developed a love of electronic music through Italian pop music of the 1980s, before discovering hip hop and acid house . He began djing in the early 90s and in 1995 moved to Dublin where he got heavily into darker, deeper electronica and electro by the likes of Autechre, Drexciya and the extended Detroit- inspired musical underworld.

Leo began producing his own music in 2000, concentrating initially on electro but broadening his range into unconventional house and techno styles. His debut release was the ‘Maike ep’ on Dublin’s D1 Recordings in 2005. He followed this up with a critically acclaimed release on Real soon, titled ‘Ruski’. Then followed the equally outstanding “Seeker ep“ on Enclave Recordings , closely followed by a release on The “A touch of class” imprint out of Germany , a brilliantly received ep on Uzuri . More recently he has released on the seminal “Millions Of Moments ” imprint as well as the ace new label , Quintessentials.

Since then Lerosa has been on demand as a remixer and has garnered a lot of press coverage from magazines such as Germany’s Groove Mag & De Bug , London’s Strobelight Honey magazine as well as coverage on the increasingly influential music blogs, such as Infinitestatemachine , Test , e.t.c.
