Campaigners in the Vale of Glamorgan have staged a concert in an ongoing protest over plans to test-drill for shale gas.
They fear a discovery of shale gas in the area will eventually lead to hydraulic fracturing, or 'fracking' - a controversial method of extracting the gas from underground rock.
During fracking, water, sand and chemicals are pumped in to split the rock, releasing shale gas.
Those opposed to it cite concerns over its potential impact on the environment, adding that there should be a bigger focus on sourcing renewable energy from wind, water and light.
But supporters, including Prime Minister David Cameron, say it could bring jobs, investment and increased energy security for Britain.
Bridgend company Coastal Oil and Gas Ltd has secured planning permission for four drilling sites in the Vale of Glamorgan and Rhondda Cynon Taf.
The managing director of the company told ITV News he did not wish to comment on the latest protest.
