Private Energy is the fifth album from Roberto Carlos Lange a.k.a. Helado Negro. Written and produced by Lange, the album is an interpersonal communication of sounds about his surroundings past, present, and future. Private Energy, which follows 2013's Invisible Life and 2014's tour de force Double Youth, continues the work Lange has done as an artist, culminating in the most captivating artistic statement of his career. The music draws from his expansive knowledge of sampling, sound synthesis, recording and history of references, and the album was created as a performance piece in tandem with his Tinsel Mammal dancers. Present at each Helado Negro show, the Tinsel Mammal dancers, costumed head-to-toe in silver strands, are a visual representation of sound and a sensual gateway to profoundly personal lyrics. The Tinsel Mammals are not representative of any human form. They work as a shimmering o bjects that represent the ideas of genderless and raceless beings and Private Energy's themes of self-love, pride, and the embrace of constant change.
