Adventurous R&B twosome S4U, aka Rosita Bonita and Prinz George, may not have a huge catalogue to their name yet, but they're already earning devoted fans in their droves.

Their latest outing is for the JD. Reid-produced "Refrain", a futuristic expansion of their already progressive take on R&B's classic moments. For his part, Reid contributes a mind-bending, woozy instrumental that's both off-kilter and surprisingly club-ready. The vocals, meanwhile, tie it all together and drive the track forward with a sultry delivery to leave the listener weak at the knees. 

To handle the visual aspect, S4U themselves stepped into the director's chair and the results are exactly the sort of brain-melting surrealism we'd hope to get from the pair. Now more than ever it's clear how profound and uncompromising the pair's creative vision is. 

More of this, please.
