I have noticed on my bazillion blogs many rooms feature amazing concert posters, and I always wonder where on earth they found them. Well somehow I stumbled on the site poster cabaret (sorry I honestly forget where I saw it!) where they have a whole lot of beautiful concert poster art, as well as many other prints. The Swell Season one above is my favourite, but there are lots of amazing choices.
I really like this Monsters of Folk one too. And just in case you thought they were all Indy Rock bands, this one is for Chris in honour of our Metallica experience a few weeks ago!
