Go to a few festivals like Glastonbury and the like.They're great to go camping with mates (usually in mud). I didn't really go for the music, just the atmosphere and the boozy lifestyle.
Also be prepared to save heaps of money for gigs. There are so many international bands that tour the UK. It's not like Australia, where you might see half a dozen good bands every year - they all go there!
Also a little tip, be prepared to lower your "standards" for chicks. There's not much talent there.
