The band consists of multi-instrumentalists Lewis Lazar, Christopher Willatt, and Julia Johansen.

Lazar said in an interview with Clash Magazine, "We were trying to find a gang name that connotated the type of music we were writing at the time.

[7] Originally, Johansen collaborated with Lazar and Willett as a singer, officially forming Oracle Sisters, but soon found her place primarily on drums.

[10] A three-song release of live versions of "Hail Mary" and "RBH" from Hydranism and "I Don't Wanna Move" from Paris II came a month before the album via OurVinyl.

Divinations, the band's second album, is set to release on February 14, 2025, via Wizard Artists, their own record label.

[11] Oracle Sisters has played at various festivals throughout Europe, plus SXSW in 2023,[12] and opened for Declan McKenna's US tour in 2023 and L'Impératrice and Colapesce in 2024.

The band brings in other musicians to fill the roles of bass and keys when performing live.
