It's from Popular Culture zine and is called 'We're Stupid But We're Happy'. It contains a rather top bunch of artists (and me) and you really should get your paws on it posthaste!
Los Campesinos - It Started With A Mixx
Former Bullies - Vampire Blues
The Answering Machine - Oh Christina
Sky Larkin - Keepsakes
The Star Fighter Pilot - Another Penny (featuring Rachael Kichenside)
Modernaire - Shall We Disco
Ed Cottam - No One Quite Like You
The Waverton Collective - Trans Siberian Express
my side of the mountain - Winter People
Sir Yes Sir - OK
Air Cav - Alliance
The Search Map - You Are The Loop
redcarsgofaster - 24 Passes
Shut Your Eyes and You'll Burst Into Flames - Signal Noise
A fine compilation, I'm sure you'll agree! You can pre-order it over at Popcult's website.
