José Manuel Alvarez, also known as Dubbyman, made his debut as a DJ in 1992 under the alias of José Vertice. Acid house, funk, drum & bass and hip-hop were just some of the ingredients of his firsts sets, backed up by his collective Dogs Connected.

Later forays into dubbed house and electrofunk sounds took him to visit the most important clubs in Madrid like Deep and Danzoo, while maintaining his own club, Freak. By 2002, and thanks to his new facet as a producer, he became Dubbyman and moved his residency from Freak to Café Bar Las Descalzas and expanded his sessions across Madrid, in clubs like Morpheus, Ohm, Taboo, and beyond in places like Le Club (Valencia), El Sol (Salamanca), Telefunken, House café, Foxx (La Coruña), La casa de la música (Badajoz).
In the ensuing years, he explored many different clubs around the world (London, Lisboa, Amsterdam, Berlin, Bratislava) and festivals such as Freerotation 2010. Before the summer break he finished with a successful week in Chicago sharing decks with Bjak & Julio Bishop from RealDeep, Daryl Cura from Eargasmic and Specter (Tetrode music).
He and his brother Above Smoke have run the Deep Explorer Music label since 2003, where they release their music and other recognized artists such as Alton Miller, Mike Huckaby, Nick Sole, Specter, Kai Alce, Rick Wade—and the list goes on.
