Oslo, Norway's Sassy 009 makes abstract electro-pop that edges toward house, techno, and industrial, mixing dreamy synth textures with distorted, propulsive beats. Once a trio, Sassy 009 became the solo project of founder Sunniva Lindgård in 2019, when second EP Kill Sassy 009 was released. Further releases like 2021's Heart Ego flirted with drum'n'bass and synthwave.

The daughter of classically trained musicians, Lindgård picked Sassy 009 as a SoundCloud username before she started making music herself. She formed Sassy 009 in early 2017 with former classmate Teodora Geoegijevic and mutual friend Johanna Orellana, and the trio started making left-field dance-pop songs filled with layered vocals and lush flute arrangements. Debut EP Do You Mind was released by Luft Recordings at the end of the year. Sassy 009 unexpectedly slimmed down to just Lindgård in 2019. She recorded Kill Sassy 009 at Luft Studios with the help of co-producer BAYA (Andrew Murray), and the EP was issued that November. Sassy 009 also collaborated with Clairo on the single "Lara," a tune about a crush on iconic video game character Lara Croft. Several singles, including "Blue Racecar" and "Mystery Boy," led up to the release of the 2021 mixtape Heart Ego. ~ Paul Simpson
