Max Richter - Les Baricades Misterieuses (composed by Francois Couperin). Kronos Quartet - Tenebrae II (composed by Osvaldo Golijov). Hagen Quartett - String Quartet No.14 in D Minor, D.810 Death & The Maiden (composed by Schubert).
This is a really nice collection of some left field music. It covers many genres from post rock to neo-classical. If you are looking for an introduction to these styles it's a good way of sounding out what you might like. If, like me, you already know your way around it's just a great mix tape.
