[3] Lange's songs are bilingual in English and Spanish and explore Latine identity, drawing on his upbringing in South Florida as the child of Ecuadoran immigrants.

The son of Ecuadoran immigrants, Helado Negro (Roberto Carlos Lange) was born in South Florida in 1980.

[7] As a high school student during the early 1990s, Roberto Carlos Lange would stay up late watching "Liquid Television" on MTV.

"Roberto Carlos Lange's sixth and best album as Helado Negro deepens and expands upon the imagistic nature of his lyrics and cosmic synth-folk.

"[19] In 2007 Lange collaborated with visual artist David Ellis to create "Trash Talk" for a Christian Marclay curated show at the ICA Philly.

Sonic trash bags created by David Ellis rattled and bumped like a percussion team, put together out of garbage bags, cans, bottles, cardboard, plastic, paper, aluminum, tin, foam, wire, hardware, and electronics.

[26] In 2011, Lange contributed a site-specific sound sculpture called "HVAC Music Box",[27] for the "Sequence of Waves" group show at Saint Cecilia's Convent in Greenpoint, Brooklyn.

The composition in the music box is an original piece that is on a continuous loop that is only advanced by turning the knobs.

The sculpture was made for a site-specific group show called Sequence of Waves that was installed at the St. Cecilia Convent in Greenpoint, NY for one day only.

Also in 2011, Lange was commissioned by Flux Projects to create a week-long site-specific installation that involved sound in a public space.

He performed four songs: "Transmission Listen", "Young, Latin and Proud", "Run Around" and "It's My Brown Skin", accompanied by a 5-piece band consisting of drums, two saxophones, violin, synthesizer, with Helado singing and playing guitar.
