After releasing four albums between 2010 and 2018, She Makes War was formally disbanded in December 2019, and she launched new a music project Penfriend in May 2020, with accompanying weekly podcast series, Attention Engineer.
John Robb described Kidd in 2011 as "a modern musical Boudica",[3] and Will Butler wrote in 2015 that she possessed "The emotional resonance of Elliott Smith colliding with the barbed vigour of Sleater-Kinney" (Gigwise).
She Makes War's first two albums Disarm (2010) and Little Battles (2012), share stories from the personal to the political, dealing with matters of love, loss, birth, therapy, murder, abandonment, and hope.
She also supported Suede, The Levellers, British Sea Power, Ginger Wildheart, Tune-Yards, Gruff Rhys, The Magic Numbers, Duke Special, Midge Ure, New Model Army, Glen Matlock and Earl Slick, Nadine Shah, Erica Nockalls and Miles Hunt, Chris Helme, Drugstore and The Posies.
Kidd has also toured, providing bass and vocals, for artists including Tricky, Viv Albertine, Lil' Chris, The Penelopes, The Young Punx and Alex Parks.
