Roberto Carlos Lange is a Brooklyn-based musician whose primary moniker is Helado Negro. Born and raised in South Florida to Ecuadorian immigrants, he was influenced early on by the musical styles of Miami bass and experimental dance music to Latin American folk songs.

He was also a member of the group Savath y Savalas, alongside musicians Guillermo Scott Herren (better known as Prefuse 73) and Eva Puyuelo Muns. He has also released two albums, Music for Memory (2009) and Plural People (2015), under his full name Roberto Carlos Lange.
