I recently heard this Michael Kiwanuka track as part of the BBC's Glastonbury highlights. Then I discovered an extended version on YouTube. And now I'm hearing it used in the Mercedes-Benz GLE - 'Long Run' tv advert. 
However his story is also interesting. He's the son of parents who escaped Uganda and the Amin regime, growing up in Muswell Hill, London. Studied at the University of Westminster. Became a session guitarist. Signed a record deal with Polydor in 2011 and has been nominated for various awards. His second solo album 'Love & Hate' was released in 2016 and reached No.1 in the UK albums chart. 
The track 'Cold Little Heart' is from that LP, but this is titled (Live Session Video) and has a long instrumental intro (not unlike 'Shine On You Crazy Diamond'). It's over 11 minutes long, so do as they do and have a cuppa tea first....
