A HEAVY metal band have been forced to cancel a gig tonight at a Southampton live music venue after their tour bus plunged 30 ft off a viaduct.

Members of Baroness were on route to play at Talking Heads in Portswood Road.

But the American heavy metal quartet were forced to pull the plug on their last stop on a UK tour after their coach lost control in heavy rain, overturned and plunged 30ft off a viaduct at Brassknocker Hill, Limpley Stoke, near Bath, Somerset.

Fortunately, the single decker landed on its wheels on a road below. But the emergency services said two people, including the driver, were trapped in the wreckage.

They were cut free and, having suffered the ''most serious injuries''.

The Great Western Ambulance Service said injuries included multiple fractures.

One, the driver, also suffered chest injuries and was taken to Frenchay Hospital. The eight passengers went to the Royal United Hospital in Bath.

A police spokesman said the coach left the road just before the Limpley Stoke Bridge and went down an embankment.

“Nine people were on board, including the driver, and all have been accounted for and taken to hospital," she said.

“Roads remain closed in the area to allow investigations to take place and motorists are asked to remain patient, as this may have an impact on traffic in and around the area.

“It is hoped the road could open later this afternoon.”

The accident happened on the A36, the main road between Bath and Southampton.
