I saw Pearl Jam Twenty a while back and thoroughly enjoyed it. The archival footage of Pearl Jam in the early days, even before the formation and demise of Mother Love Bone is excellent. If you are a fan of Pearl Jam or of the Seattle music scene in the late 1980s and 1990s, you'll likely enjoy this film and the music that is its heart.
This project, sometimes also known as PJ20, was conceived by, written and directed, and occasionally filmed by Cameron Crowe.
