About

Sister Aggie are a four-piece alt-rock/indie-pop band from South London. Jonny (vocals, rhythm guitar), Jake (lead guitar), Dec (drums) and Isaac (bass) blend melody and drive with the grit and groove of modern guitar music.

Their sound moves between clarity and chaos – layered guitars, pulsing rhythms and moments that hit hard. On stage, Sister Aggie are electric: high-energy, immersive and unafraid to lean into the dirt. Each performance leaves audiences buzzing, drawn in by the band’s intensity and sense of release.

Rooted in friendship and shared instinct, they make music that’s grounded and direct – songs that connect, lift and linger long after the lights go down.
