AM pretty sure this track came out in the last few years, though it is obviously heavily influenced by 70s disco. It has a central violins riff reminiscent of Bony M, Sister Sledge, Abba or the Bee Gees. I think the riff might segue from strings into trumpets or horns at some stage. The vocals sound like a black man's voice to me, soulful, bluesy and beautiful, rather high and something almost Nina Simone about them. Its a long track, at least 5mins imo.
Please help!
