We're a power trio consisting Arthur Brown (guitar, vocals) and brother and sister Jordan (drums) and Lily Cook (bass, vocals).

We play stripped down garagey pop songs with a loud psychedelic sound.


Formed in their home town of Bristol, GuMM consists of Arthur Jay Brown (guitar, vocals) and the sibling rhythm section of Jordan (drums) & Lily Cook (bass, vocals).

After rehearsing and keeping in the shadows for several months, GuMM launched themselves with shows for Vice Magazine and played alongside Splashh, Wooden Shjips, Eagulls & Novella whilst gaining acclaim & attention on the blog circuit and in publications such as Artrocker, DIY and Fly magazine. They were also a Great Escape Festival band of the day.

GuMM recorded their debut single 'Lionheart' at Portishead's studio with producer TJ Allen (Bat for Lashes, Roxy Music & Portishead) and released it through Howling Owl Records in the winter of 2012.

GuMM produce droning, psychedelic pop songs with a garage ethic that packs more than a noticeable punch.
