Metallica will headline Glastonbury on Saturday June 28. It's been a huge talking-point leading into the event, with artists from Jarvis Cocker to Alex Turner having their say on the controversial booking. NME's spent time on the road with the metal legends in the run-up to the event. Check out our exclusive photographs.
NME writer Barry Nicholson went behind the scenes with the legendary rockers last month in Stockholm, Sweden for NME's Glastonbury preview issue of the magazine.
Metal bands have rarely played the Somerset festival, leading to Kasabian calling Metallica's headline spot a 'brave move' and Arctic Monkeys saying they support it, but saying it 'doesn't add up'.

"Whichever angle you view it from", writes Barry Nicolson of the Swedish gig, "they are a truly spectacular live band."

Glastonbury's not known for booking 'heavy' bands, but some artists who've played at Worthy Farm in the past include Rage Against The Machine, Tool and Nine Inch Nails.
But only three previous Glastonbury headliners - Bruce Springsteen, U2 and The Rolling Stones - have sold more records than Metallica's 100 million, writes Barry Nicolson in NME this week.
"When we play live, that's when you see the real us. We tend to win people over, even when they don't wanna be," says James Hetfield.
Metallica play for over two hours in Sweden. The show was a 'By Request' affair, with the setlist chosen by fans online.
What'll the band play at Glastonbury? NME expert Ben Patashnik hopes for 'Orion', Tuesday's Gone', 'Hero Of The Day', 'The Memory Remains' and 'Of Wolf And Man'.
The STHLM Fields show featured solos from Rob and Kirk, which can be expected at Glastonbury. Pick up this week's NME for a full interview with the band.
