Nick Mono's casually melodic songs combine a wide range of influences, from alternative rock to pop to hip-hop, with a late-'90s slacker vibe. After releasing his first EPs, the Londoner garnered attention with his song "Effy Stonem" in 2020, when he was still a teenager. Following the track's success, Mono signed with Parlophone and released another EP, The Sun Won't Stay After Summer (2022).
