Travis Biggs was a keyboardist who caused Isaac Hayes through the late ’70s, an interval that found Hayes flirting with disco. Biggs also released two spacy, synth-driven LPs of his very own during that period: 1976’s Problem, on TB&C, and 1979’s Solar Funk, on MCA subsidiary Supply. He is greatest appreciated for the much-sampled cut “Tibetan Serenity.”
