Want Me - Affelaye Snitch - Antonio Pinto Florid (Brambles Remix) - Benoit Pioulard Mirror Maru - Chasmere Cat Mt Wolf Life Size Ghosts - Catching Flies Cold War (Nick AM Remix) - Cautious Clay We Can't Be Friends - Dream Koala Unfaith - Ekali Mood Swings - Frederic Robinson Symbian (Christopher Rau Remix) - Freund Der Familie Brooklyn Baby - Frumhere Time - Hanz Zimmer Resonance - Home October - Icarus Thousand Yard Stare - Illum Sphere Comrade - Island Fox Another Girl - Jacques Greene Ghostly - Jasper Ryom At Dawn - Joe Hertz Monsters Theme - Jon Hopkins Sounds of Her Mind - Just A Gent Track Uno - Kaytranda Bus Rude - Kaytranda Looped - Kiasmos Trust (Christian Loffler Revision) - Max Cooper & Tom Hodge Shifted - Mazde Wanderlust - Melodiesinfonie New Horizon - Moods Love Is Real - Moods Dryland - Nebulae Colomb - Nicolas Jaar Sun Models - ODESZA How Did I Get Here - ODESZA Sunday - Oliver Schories Cheated - Pascaal Drowning In You - Pascaal Sunset Lover - Petit Biscuit Juju - Ras G E Isso Ai - Sango Three Sided Shape - Scuba Places - Shlohmo Eiszauber - Solomun & Stimming Truth - Submerse Walking With Elephants - Ten Walls I Learned - Wondr Crunch - Xjk Intro - The xx
All their video's have a similar 'vibe' to them, you should check some of the others out. Genki Sudo (yes the kickboxer/martial artist) started the group and while they have catchy music too they were more about the 'dance'.
