Kasabian's Serge Pizzorno admits he doesn't know any of Metallica's music.

The 'Eez-eh' hitmakers will be headlining the Glastonbury festival alongside Arcade Fire and the legendary heavy metal band next week and they think the group are a ''controversial'' booking.

Serge said: ''Metallica, they're massive. I'm being entirely honest with you, I don't really know their tunes but they're massive.

''They've been doing it for a long time, so they'll have a few tricks up their sleeves. It's been quite a controversial choice but I think that can also work in your favour. I've met Lars [Ulrich], the drummer. He came to a show of ours in San Francisco and was a lovely chap, so I wish him all the best.''

However, the band - also made up of Tom Meighan, Chris Edwards and Ian Matthews - have been checking out Arcade Fire and are a fan of their album 'Reflektor'.

Serge told NME magazine: ''I've only seen little bits of pictures and stuff but they seem like their live show is interesting. They seem like a great band for a Friday night.''
