Luxembourg's Sam Skilz and Miss MAD unleash their fourth collaborative release, 'Behind The Doors', with 2 potent progressive house cuts for GaGa Records. 'Behind The Doors' is atmospherically haunting, armed with a catchy melodic hook, airy synth waves, a brooding bass and tension filled drops. Ramping up the feel good factor is 'Connected', laced with celestial synth melodies and an infectious hook that cheerfully twirls over a slamming groove.
