Biggest Weekend: More acts announced for BBC's music festival

Wolf Alice are among the 27 acts added to the line-up

Craig David, Niall Horan, Wolf Alice and percussionist Evelyn Glennie have joined the line-up for the BBC's Biggest Weekend festival.

They'll appear alongside the likes of Ed Sheeran and Taylor Swift at the one-off event, from 25 to 28 May.

Partly designed to fill the gap in the festival calendar left by Glastonbury's fallow year, it will take place in four locations across the UK.

Tickets go on sale on Monday, priced at £18, plus a £4.50 booking fee.

Designed to show the breadth of music available on the BBC, the Biggest Weekend will be curated by each of the broadcasters' music stations: Radio 1, 2, 3, 6 Music, 1Xtra and Asian Network.

"It's a one-off moment in history, which hopefully we will all remember."

The BBC announced 27 further acts on Wednesday, ranging from dance act Orbital to jazz star Jamie Cullum.
