John-Paul Pirrello (born 27 December 1984; in Sydney, Australia), known onstage as Outbreak, is an Australian DJ and music producer.
In his initial years, JP Pirrello performed under the name NitrouZ and released tracks "City Bitch", "Crazy Music" with DJ Duro and "Lonely Dark" with Zany, which were picked up among many fans worldwide.
As NitrouZ, Pirrello performed at many parties in Australia and The Netherlands such as Defqon.1 Festival, Dance Valley, Q-Dance: The Next Level, X-Qlusive Showtek, Q-BASE, Euphoria and many more.
In 2013, the alias NitrouZ was discontinued and Pirrello re-launched himself as Outbreak, signing to Brennan Heart's record label, WE R Music and representing its sub-label WE R Raw.
