The Cooper Temple Clause are to perform a gig in support of a new bands competition called Unsigned Heroes.
The band will play London’s KOKO alongside three competition winners on April 26.
The final stage of the competition is a ‘vote off’, during which the bands will be whittled down the winning three.
Over 800 bands initially took part in the competition.
The winning acts will be announced on Unsignedheroes.co.uk on April 2.
Whoever is triumphant will get a recording session with a big name producer, PA equipment worth over £10,000 and the chance to play a major summer festival.
The shortlist of 20 bands is:
Catch It Kebabs
The Dirty Lips
The Storm Of Eighty-Three
The Great Statesmen
