Roberto Rey, known in the music scene as Negocius Man, was born in 1980 in Madrid. His exciting journey in the world of music began in 1997 when he took his first steps as a DJ, and two years later, in 1999, as a music producer.

His musical beginnings are located in Hiphop of the 90s and Electro of the 80s and 90s. In his early years, he was part of the Hiphop group MFD2 along with artists such as Mackfrank, Darmo and Julia, under his alias of Dj.Say.

Negocius Man stood out on the Madrid scene, performing in iconic venues such as Kea, Davai, El Sol, Caracol, Siroco, Specka, Yasta... and CSOA's such as Seko, Laboratorio or Tabacalera. At the national level, he took his music to places such as Sala El Grito (Murcia), El Arrebato (Zaragoza), El Orritxo (Bilbao), Sala Arco (C.Real)... and events such as Three Monkeys Fest, Hifi Fest both in Guadalajara, Electrocamp (Valencia) or Nuit Pastel (Francia).

In 1999, he began his first contact with hardware equipment, such as the Roland MC303, and software such as Fruity Loops and Fasttracker 2, thus marking the beginning of his career under the alias Negocius Man since 2000.

Throughout his career, Negocius Man experienced a significant musical evolution. In 2005, he largely disconnected from the world of Hiphop to delve deeply into Electronic music. In 2007, he took a bold step by creating his own club, "THE KINGS_ELECTROBAR", in Alcázar de San Juan (C.Real), where he made valuable contacts in the scene.

In 2009, he made the decision to acquire new hardware and returned to Madrid. Since then, he has released music on various notable labels such as Fundamental Records (Madrid), Mars Frequency Records (Madrid), Bankai Records (C.Real), Binalog Frequency Records (Greece), Beathazard (Bcn), Eclectic Reactions Records (Bilbao) , Elektrodos (Zamora) Electroclub (Bcn), Urban Connections (Jaén) Crobot Muzik (London/Croatia), Subsonic device (Germany), Syntax & HC records (Valencia), Frigio Records (Madrid), Nawal / Baox (Mexico), Oráculo Records (Bcn) ... etc.

In 2014, he launched his own record label, MICROM RECORDS, cementing his status as an influential artist in the national and international electronic music scene.

Over the years, he has shared the stage with a long list of artists such as: Awco, Waje, Dj.F. Groof, Juanpaplo, David Aragón, Durban Noise, Robert Cosmic, Zenobit3, Julia Pe, Sace 2, Bas Madrid, Eleztrik Body, MEKA, SEEK2012, Darxid, Lektroid, Arch, Fer Xploxion, Antoni Maiovvi, Hyboid, Mauro Nakimi, Vema, Spy, MSKS, Wavelet, Elektrogena or Dani Surco among others.

Negocius Man remains a leading figure in the electronic music scene, leaving his distinctive mark on music and continuing his exciting sonic journey.
