A music video has been released that was directed by Heath Ledger shortly before he died from an accidental drug overdose at the age of 28 in Jan. 2008.

Rapper N'fa Forster-Jones posted the video for his song "Cause An Effect" on his YouTube and MySpace pages on Thursday.

"I, everyday, count my blessing every day for the fact that I got to have him direct this piece of art," Forster-Jones says in a YouTube video explaining the experience. The rapper and "The Dark Knight" star were childhood friends growing up in Perth, Australia.

The late actor's final film "The Imaginarium of Doctor Parnassus" opens in theaters Dec. 25.
