I just discovered this very cool, online music lesson site. They offer guitar, keyboard and drum (drumkit) lessons. It's all pop music, but I love the concept. They are compiling a catalog of video lessons for songs, where you learn the song by watching how the chords are played. It's ingenious, and it looks like its got some really good backing. If you've every struggled to learn to play a song by listening to the CD, this will be a huge help. The lessons are well thought out and presented.
Here's a like to their Acoustic Guitar lessons feed: http://stream.ivideosongs.com/podcasts/itunes/ivs_acousticguitartechniques.xml
