Don't make a mistake with the avatar above. The music of El Macaquito is entirely provocative and dirty. The project is result from ghetto and its sound blends hip-hop, bass, electronic and brazilian rap. All tracks with themes involving insanity, riot, policy, eroticism, human behavior, retro, futurism and sci-fi. The result is a funk carioca sofisticated, but few hits at the slums of the Rio. To produce, he use laptop, sampler, vinyl and keyboard. Behind nickname El Macaquito, Romulo Castor also produce other bass-heavy rhythms like Jungle, Dance Hall and Gabber.
