Whether it’s through their embrace of electronica or use of innovative digital avatars, futurism has always been a key cog in the Gorillaz machine. So it’s doubly impressive that this collection sees them revitalize something as outwardly old school as the B-side compilation. Whipping restlessly from the caffeinated bounce of “19-2000” (Soulchild Remix) to the twitchy blues of first ever recording “Ghost Train”, G Sides is an experimental snapshot of a collective with creativity to burn.
