The Gaa Gaas are a British rock band from Jersey in the Channel Islands, now based in London and Brighton, United Kingdom.

The band formed in 2003 after meeting at a garage punk club night called 'Bomp', a weekly event held in their hometown of St. Helier. The idea for the direction of the group came after attending a tour that consisted of The Eighties Matchbox B-Line Disaster, The Parkinsons, and Ikara Colt. They have gone through numerous line ups since their original three-piece formation remaining relevant throughout the groups two decades of existence.

Since the group originally relocated to Brighton, they have toured throughout the UK and Europe. They contributed a cover of 'Ca Plane Pour Moi' originally by Plastic Bertrand on the compilation 'Nineteen78' by Filthy Little Angels Records released in 2008, and then signed to The Playground Records releasing their debut single 'V.O.L.T.A.I.R.E.' in 2010, later to be re-released on the groups own label Movement-2 Records. They have received broadcast from BBC Radio 1 and MTV 2, featured in the new blood section of Artrocker magazine, and performed the launch event of Brighton's popular club night 'Stay Sick!'. They were headliners on the second stage of the last ever Jersey Live Festival in 2016 performing after Richard Ashcroft the former frontman of Wigan rock pioneers The Verve had just finished his performance on the main stage. They also appeared at Drop Dead Festival in Lithuania, an event that originally started up at the legendary New York club CBGB.
