SISTRA
SISTRA
SISTRA is a London-based art-pop and hyperpop duo formed by classically-trained sisters Sasha and Sylvie Briggs — Sylvie trained in voice and piano, Sasha in violin and guitar. They officially launched SISTRA in 2023 after posting covers online during lockdown, and work as songwriters and producers rather than primarily vocalists, crafting emotionally charged, genre-blurring electronic pop that explores sisterhood and identity. Their debut album "She Won't Let Go" (May 2026) was executive-produced by Jon Shave (co-producer on Charli XCX's "Brat") with contributions from hyperpop pioneers Danny L Harle, Micah Jasper and Chloe Kraemer. SISTRA have earned early support from BBC Radio 1, played sold-out headline shows, appeared at All Points East and toured alongside Rose Gray. They are signed to AWAL, with management by 724 Management and live booking through Wasserman Music. Their sound leans into avant-pop, dream-pop and abrasive-yet-melodic hyperpop textures.
