Martinez, by birth Martin Swanstein, was born in 1981 and raised in the southernmost part of Sweden. At an early age he discovered techno and house music. Since he already played various instruments it was a natural progression to begin producing music himself. He also got into DJing and started hunting down techno records and got into mixing. Some years later, a demo tape earned him the opportunity to develop his production skills in the Wrong Steps studio in Stockholm, where he co-produced some of his own tracks together with the French producer Manuel Perez. One of these early tracks later appeared as “Late Night Groove” on Martin's debut 12" on the Swedish label Deeplay Music.
In 2000 Martinez moved from his small hometown in Swedish to the more open musical climate of the Danish capital, Copenhagen. This encouraged him to put even more time and energy into his music productions and not long after this he landed a record deal with the renowned Guidance Recording label in Chicago. First out was the “Laidback Grooves EP” with its mix of Deep House and Broken Beats and two more EP were to follow. Martinez earlier work includes remixes for Danish pop/house act Filur as well as Silicone Soul, Jussi Pekka, Dibaba, Spiro Projecto and later Underworld, Luna City Express, Miss Kittin, Mathew Dear & Seth Troxler, Joel Mull, Leon and his remix of Nathan Fake's “The Sky Was Pink” was a big hit in the DJ world.
