The concert, currently livestreaming from the Hammersmith Apollo, is directed by filmmaker Hamish Hamilton. The performance comes in anticipation of the release of his album Looking 4 Myself, landing in stores tomorrow.
The LP marks his seventh studio release. The project features guest appearances from Rick Ross, Pharrell Williams and Empire of the Sun's Luke Steele, who also produced the title track.
