Coming from Torrelavega, a small city in the north of Spain, Roberto Perez was strongly influenced by the local hip hop scene in this area.That provided the catalyst for his first foray into beat production and scratching, collaborating with local rappers as a DJ and producer on albums and live concerts. A moving to Madrid and consequent study of "Sound Arts & Production" forced his deep love for Electro. Robert Cosmic shared great success on different electro labels and established his own brand with "Mars Frequency Records" in 2010.
