The American phenomenon CeeLo Green is not only a soul singer but also a songwriter, businessman, TV personality (including on The Voice), and fashion icon. Under the name Gnarls Barkley (a collaboration with producer Danger Mouse), he created the song Crazy (2006), one of the biggest hits of the 2000s. Four years later, he repeated that success with F**k You. With a new Gnarls Barkley album (Atlanta) out and six solo albums under his belt, CeeLo Green has plenty of material to choose from tonight. To quote his second album: Cee-Lo Green... Is the Soul Machine!
