"Bringing back the '80s" is proudly displayed on 22-year-old Poland-based producer Chloe Martini's Twitter biography. One listen to 'Unknown' and you'll find that she's not lying.

'Unknown' sounds like something you'd hear on one of those excellent late '80s, early '90s movies that you've seen a million times but still go back to when nothing else is on TV (Think Boomerang, House Party etc). The bass guitar licks, drums and keys all scream '80s, while the vocal talents of London born, LA based singer/songwriter Shae Jacobs (who has previously written for the likes of Kelly Rowland, Chris Brown and Teyana Taylor with producer Harmony Samuels) add to the beauty of this soulful number, which is taken from Martini's debut EP Private Joy.
