For some unknown reason despite Mogwai ticking every post-rock/epic noise/guitars set to stun/shoegazing for grown-ups box I could ever hope for, I only own a few random albums - Government Commissions, Come on Die Young, The EP thingy with Stanley Kubrick on it and recently Mr Beast. This is essentially what happens when you refuse to organise your listening needs

Which is their best album and do I own it?
