I've received some nice feedback on the design of the site and I'm glad people like it. The background image used throughout the site I have to thank Martin Fisch for. He takes some lovely photos as you can see on his profile. The photo used in the background is this one.
He has let me know that his creative commons work is free and he'll be happy if any musician wants to use his work. Whether you're a Block Label artist or not, if there's anybody who would like to use one of them as their cover art they're free to do so.
Give credit where credit is due and send him a quick message to thank him if you do so - it's always nice to know when one's work has been appreciated.
Here's a few from his collection:
