My dad got the Joe Strummer documentary, The Future is Unwritten, from one of his employees for Christmas. It's put together pretty well and really gives some insight into how important Strummer was to punk and pop music as a whole.
Watching the documentary also got me to dig out the records he made with The Mescaleros at the beginning of this decade. I loved these albums when I was in high school. Strummer was grabbing from numerous genres creating some great work before his untimely death in 2002.
They're certainly worth your time if you were a fan of The Clash or just well made rock 'n' roll.
