The US musician was performing at Alexandra Palace for the Vans Warped Tour when he jumped 30ft from the rig into the audience.
The crowd reportedly parted in an attempt to avoid impact but Watsky ended up breaking one girl’s arm with another man hospitalised.
Watsky escaped with minor injuries telling fans he was ‘fine’ in a message on Facebook apart from ‘some nicks, bruises, and the shame of endangering the crowd’.
The video is pretty insane!
