(TheWrap) — In a music industry long dependent on black performers, the expected appointment of two African-Americans to top executive roles at the major labels is unlikely to be viewed as much progress. The appointments will follow back-to-back exits by the industry’s most visible black executives. They’re also occurring in tandem with a decline in black music itself. Most likely, they will only spotlight the continuing disconnect between African Americans’ meager power in the industry’s management hierarchy and their sweeping artistic influence. By month’s end, “Gee” Roberson (left) will be announced as chairman of Geffen Records, according to two persons close to the matter. Having co-managed hip-hop newcomers Kanye West, Lil Wayne and Drake to pop stardom, Roberson now will turn to rebuilding a stagnant brand that once reigned in rock.
