He uses Donna Summer's singles "Love to Love You Baby" (1975) and "I Feel Love" (1977) as examples of the ever present relationship between the synthesized bass lines and backgrounds to the simulated sounds of orgasms Summers echoes in the tracks, and likens them to the drug-fervent, sexually liberated fans of disco who sought to free themselves through disco's "aesthetic of machine sex." Shapiro sees this as an influence that creates sub-genres like hi-NRG and dub-disco, which allowed for eroticism and technology to be further explored through intense synth bass lines and alternative rhythmic techniques that tap into the entire body rather than the obvious erotic parts of the body.
