The Glastonbury Festival is launching a regular gig night to give new bands the chance to earn a slot at the legendary music event.
Emily Eavis is launching the Holy Cow night in London on Wednesday
New and unsigned acts are being sought for the Holy Cow night, with the best to be offered places at the festival.
"As a festival, we would really like to lead the way in new music," said Emily Eavis, daughter of festival founder Michael Eavis.
Envy Corps and Vampire Weekend play the first gig at The Social club in London.
Ms Eavis is now looking for new talent to play at future Holy Cow gigs after the launch on Wednesday.
"We're really after unsigned acts and finding the best new acts from all corners of the country and beyond," she said.
The chosen acts could end up playing on the Pyramid Stage
The most impressive bands will be booked for one of the festival's smaller stages, with Ms Eavis hoping to uncover artists who will star on the main stage in the future.
"The aim is to collect as many new bands as possible throughout the year and build up a strong roster of new acts," she said.
"We've had some brilliant debut sets throughout the years, where bands start at Glastonbury on a very small stage and end up playing the Pyramid in a few years."
Acts wanting to appear at Holy Cow should contact organisers via Holy Cow's MySpace site. The next festival will take place in Somerset from 27 to 29 June 2008.
