The Parisian Axel Monneau, aka Orval Carlos Sibelius, has made a career out of meshing bewitching melodies with ‘60s psychedelia. His 2013 album ‘Clapping Music’ is a bold display of his retro-modern mash-up style, taking in everything from straightforward pop hooks to krautrock references. Catch him at the Winter Camp festival, as part of which he’ll be playing one date at the Trianon.
