Some of my favourite albums of the year and the ones that I expect to listen to for some time to come were classical recordings. I love Beatrice Rana's recording of Bach's Goldberg Variations. She makes the aria sound like Chopin. In no particular order:

Hans Abrahamsen: String Quartets
Beatrice Rana: Bach Goldberg Variations
Debussy: Sonates and Trio
Gérard Pesson: Blanc Mérité
David Hudry: Durchgang
Ben Frost: The Centre Cannot Hold
LCD Soundsystem: American Dream
The War on Drugs: A Deeper Understanding
Maria and Nathalia Milstein: La Sonate de Vinteuil
