Libertaire, Acton's newest live music club and venue, has launched a search for the best live bands in the capital.
Artists are invited to submit their music for consideration in the venue's Battle Of The Bands.
The competition will run for 15 weeks from December 8, with a break of two weeks for Christmas.
Every Monday, four bands will compete on stage at Libertaire for a place in the semi-final and the final of the competition.
The 16 winners will qualify for the four quarter finals until there are four winners in the grand final.
The audience will be voting for their favourite band and judges will measure the vote according to the noise made by fans when the name of the band is called at the end of the show.
Judges from the music industry will be also be voting, which will give the bands valuable exposure to senior executives from the music business.
Prizes include a day's recording and mixing time in a world-class recording studio in London.
