There's something about Pink Floyd and Beatles albums that make them so perfect for LEGO remakes.
Probably partly due to the fact they're so iconic, and (in the case of the the former) there's rarely any need to have the (fairly homogenous) looking mini-figs on the cover.
I dread to think how the next generation is going to manage this same feat. There's no album covers, as such, just a photograph of the artist is a state of woeful undress. (Rihanna, I'm looking at you! Literally ;)
