An Australian rapper who was a boyhood friend of Heath Ledger has released a music video the star directed shortly before his death. N'fa Forster-Jones posted the 3 minute, 31 second-clip for his song “Cause An Effect” on his YouTube and MySpace pages Thursday, along with a video in which he explains how the project came about. Ledger shot a handful of videos for low-profile artists he liked. Ledger died aged 28 in New York from an accidental drug overdose in January 2008. Forster-Jones, who had been friends with Ledger since they were toddlers said the video was shot in Ledger's beachside apartment.
