Jake Shimabukuro: Life on Four Strings (PBS)
The PBS documentary on Jake Shimabukuro is pretty interesting.
Jake stumbled into international ukelele stardom from an anonymously posted YouTube video. The documentary would be better with more music and less talk, but you can find lots of his performances on YouTube, including an entire 77 minute concert + Q&A session recorded at Google.
He gets sounds from a ukelele that you never guess possible.
