I'm a very vocal and unabashed fan of 80's music. It's what I grew up with, never stopped listening to and it seems to be making a big comeback (Interpol, The Killers, etc.).
M83 is a band that seems to love The 80's a LOT more than me. Their music takes from all of the classic New Wave artists that dominated the 80's (OMD, Pet Shop Boys, Thompson Twins, a-ha, etc.) and ends up sounding like a soundtrack to all of the great John Hughes films from that decade. They've got a new album coming out called "HurryUp, We'reDreaming" and I was lucky enough to get an advance copy...and it's amazing. It's a double album filled with some unbelievable songs. It comes out next month and you should really look for it. If you're a fan of that era, it won't disappoint.
In the meantime, check out their last album, "Saturdays = Youth", which is pretty awesome as well.
