CTRLer (controller) is the musical project of Spanish musician J. Influenced by european new electronic trends, CTRLer began experimenting with complex sounds after his experience in several bands, mainly in the industrial rock band Jennifer in Latex. He has been developing music based on distortion, fast loops and poweful breaks, but always with melody in mind. Finding himself disappointed with the music industry, J created his own label called Error Deluxe Records in 2004. In this label, he releases most of his music.
