Electronic musician Laurel Halo will put out an EP called Spring under the name King Felix, clearly an homage to the other King Felix, Seattle Mariners ace Felix Hernandez. Or, maybe not. But, the whole Spring thing, with spring training wrapping up? Indulge me. Listen to the first track from that release, the big, churning “Spring 01,” at Pitchfork. The Spring EP is out 4/10 on Mute’s new imprint Liberation Technologies.
