Jamie Price, the son of the dance music star Goldie, was involved in an altercation with 21-year-old Marlon Morris, from Pendeford, in Wolverhampton city center in the early hours of August 24 2008.
Morris, whose left arm was in a sling following a motorcycle accident, died from a stab wound to the heart.
The incident happened at about 3.30am in Broad Street, where much of the city’s nightlife is concentrated, according to officials.
Price, from Heath Town, Wolverhampton, was convicted at Nottingham Crown Court, West Midlands Police said.
The case had been re-tried in Nottingham after the original trial at Wolverhampton Crown Court last August collapsed due to an issue with the CCTV evidence.
As it is expected, Price, 23, will be sentenced at Nottingham Crown Court tomorrow.
