On 7 February 2019, Helado Negro was a guest on RVNG Intl. Presents Friends & Fiends. Helado Negro has been played on NTS over 50 times, featured on 51 episodes and was first played on 26 November 2014.

Helado Negro is the pseudonym of North American musician Roberto Carlos Lange (born 1980 in Florida, U.S.A.).

His parents were immigrants from Ecuador, but Roberto grew up in the materialistic lifestyle of southern Florida, U.S.A. Pounding bass beats from passing cars, boom boxes bouncing down the block, and late-night parties provided a foundation for Lange’s interest in sound.

Lange has collaborated with visual and sound artist David Ellis to compose a new series of kinetic sound sculptures. These include typewriters that self-type the lyrics to Grand Master Flash's "The Message" (in rhythm to the song, none-the-less), musical owls drawn out of liquor bottles, owl costumes made out of straws, flying musical birds, motion paintings, and trashcans (full of trash) that are actually living drum machines. Lange has also worked with Paul Duncan and Bear in Heaven as well as famed music producer Guillermo Scott Herren to produce Prefuse 73 and Savath and Savalas as an active member and contributor.

Lange's other projects include ROM, Epstein, as well as Helado Negro. Epstein is Lange's “beats and loops” project, a friendly beast born of the MPC sampler. Epstein's wildly prolific output, including a series of digital releases, full-lengths, and a remix album, is a gauzy, sunny kind of dance music that references DJ mixing, summertime block parties, and mellow compositional noise.

Helado Negro began when Lange moved to New York in 2006. The early group concept grew through projects and experiments Roberto would conduct while recording himself and others in his home studio. Loops, computer synthesis, record samples, and live instruments provided the foundation for the first full-length, Awe Owe, a vibrant, shimmering, full-band Latin psyche-funk-folk epic.

After taking time to create a new series of sound sculptures, release a Helado Negro EP, score one film and begin work on another (based around his animation), Lange recently holed up in a cabin in the Connecticut woods to record the follow-up to Awe Owe. Canta Lechuza is the latest incarnation of Helado Negro and its sound may come as a surprise. Gone is the big collaborative group jam of previous work and in its place is Helado-Negro-as-intimate-solo-project. Canta Lechuza feels like the place it was recorded—its vocals and beats and synth lines coming together to craft a warm, buoyant, comforting electronic dance sound, an effortless, personal thing anchored by Lange's warm, earthy, conversational voice. Based around field recordings and live instrumentation fed through computer processing, Canta Lechuza is a thoroughly modern affair.
