There aren't many artists who can say that three out of their four first albums were shortlisted for the Mercury music prize, but such is the understated genius that is Laura Marling. Debut Alas, I Cannot Swim was written and recorded whilst Marling was still a teenager, and was an astoundingly robust collection of whispered, winsome melodies. Once I was an Eagle shows a gain in maturity for Marling. It lost out to James Blake in the Mercuries, but basically it should have won. Proper good. On vinyl or CD.
