Few tracks hit you with such emotional depth as L.A.-based Australian musician RY X’s “Berlin.” A mixture of Bon Iver and fellow Aussie Matt Corby, “Berlin” is sparse, introspective folk with a deep emotional pull. Backed only by his searching acoustic guitar, RY X’s yearning vocals and Corby-esque “woos” fill the void left by the lack of instrumentation, conjuring a magical piece of musical perfection that you won’t soon forget.
