Prince performs "Purple Rain" as the opening act during the 46th Annual Grammy Awards show on Feb. 8, 2004 at the Staples Center in Los Angeles. The Prince estate and its new partners at Sony Legacy have announced a new plan to issue a batch of old videos every week through mid-December from the Minnesota music legend’s 1995-2010 era, a period of recordings that Sony now oversees and is marketing again.
