I have managed to meet the British band Enter Shikari several times after gigs and at signings etc. Here is a picture of their new album Common Dreads (reached no.16 in the UK album chart, but I think number 2 in the itunes chart!) which I had signed by all 4 members at a signing in London in June.

I have met them other times and had different things signed but most just by 1 or 2 members at a time. If anyone is a fan of them and would like to meet them it isn't always necessary to go to a signing, the band are all very friendly and it is easy to meet them after a show as they usually come out to hang out with fans. They are my favourite band and are always so nice to fans :D If you've not heard of them I'd reccommend checking them out, they're currently touring the USA but are back in England later this year. www.entershikari.com
