What happens at a album launch party?

It's a chance for you to get to see a band live and meet and chat to the band members after have a few pints and a bit of craig.I have been to a few and once got a free copy of the album being launched but thats about it.they are usually hoping you will buy one.It's the kind of night you get to mingle and chat to everyone and meet good people.Enjoy,they are always a good night out.As long as you like the band that is.
