Beginning his fledgling DJ career in mid-late ‘80s Madrid, Mulero became a driving force in the emerging Spanish electronic music scene, building a reputation nationally with a sound built on dark and industrial foundations: Gothic Rock and EBM giving way to hard, acid-tinged techno in the ‘90s. As a key figure in its development, Oscar has always absorbed new trends and kept his finger on the pulse of electronic dance music, from the end of the 80’s right up to the present day.
A prolific producer with over 40 12’’ releases under his belt, he has also produced three albums, including 2012’s Black Propaganda on his own Warm Up Recordings- a stark, desolate techno excursion triggered by the economic situation in Spain. Developing into an increasingly established international name around the turn of the millennium, it could be said that Mulero’s music continued to mature but never mellowed, retaining the intensity of his banging ‘90s sets whilst becoming increasingly sophisticated and, in recent years, spacious in its sound design.
He runs his very own Warm Up imprint since 2000 and the Pole Group Records label since 2004. From 2013 he started working in live A/V performances under several project names like Light and Dark or Biolive. 2017 celebrated the 50th releases milestone for his Warm Up Recordings, compiling the previously released stuff on the Pattern Series with brand new remixes. On 2018 he released ‘Perfect Peace’, his next album this time totally experimental with no dance numbers, no upbeats.
'Some of Oscar's tracks... seemed to unravel themselves almost organically, as the kicks and hi-hats fluttered through the room, hitting you at various different heights and angles.'
