Roberto Carlos Lange, the being behind Helado Negro, has cultivated an untraditional approach to song craft that places his voice on an adventurous impulse without shying from familiar pop appreciation. Born in Fort Lauderdale, Florida to Ecuadorian immigrants, Lange’s childhood was suffused with tropical heat, humidity, and hurricanes, all refracted by the rich sounds and colors of the Latin American cultures in southern Florida. Exploring the expressivity within intense states of being, Latinx identity, and pluralistic sensibilities, Helado Negro’s latest album, Private Energy (RVNG Intl.), is an engrossing statement achieved through lyrically personal and political avant pop music. Often performing between two costumed, choreographed humans he calls Tinsel Mammals, Lange’s live show contemplates the delicate balance between performance art and musical performance.
