Prison Affair are portrayed as leading figures in egg-punk, a playful, fast-paced and deliberately lo-fi strain of DIY punk. The article argues that their music, visual identity and independent approach have helped turn a niche internet-born scene into an international community, while preserving its anti-polished, humorous character.

Based in Barcelona, the band have released four short demo EPs between 2019 and 2024 rather than a full-length album, with most tracks lasting under two minutes. Their sound combines distorted vocals, heavy bass and synthesisers, and their DIY influence has expanded through Prison Records, whose first release was by Leeds band The Oidz.
