Serge Pizzorno has an ''evil twin''.
The Kasabian rocker admits new track 'Treat' is inspired by another side to his personality, and though it sometimes leads him into trouble, he ''buzzes off'' his mischievous persona.
He said: ''The lyric about my evil twin is that moment when you have one beer and you make certain decisions.
''After two beers decisions can still be made but after five or six beers you are a completely different person. But there is something amazing about the other person, your evil twin.
''Although he, or she, will get you into more trouble than you are ever likely to get into, you do buzz off that other person a bit.''
The group headline Glastonbury this weekend - 10 years after they opened the event on the Other Stage - and claim they always knew they would top the bill.
Serge said: ''We knew we'd headline it one year and now we're closing the festival. We've come full circle and silenced our critics who saw us as a lad band when we are anything but.
''We keep coming out with stuff that f**ks with people's heads. When you are confronted with confusion, people hit out.
''What we are doing is new. There hasn't been anyone like us.''
