Every Good Boy Does Fine: A life in piano lessons. [SLNewYorker]
MusicMoose wants "to provide the world with free, useful music lessons, and a community based site to help back it all up." The site contains hundreds of free video music lessons (often containing notation and/or tablature) with a distinct focus on acoustic and bluegrass music, all taught by some pretty badass pickers (including the astonishingly good mandolin shredder Anthony Hannigan). There are also obligatory but very useful forums. Takeaway: the whole thing is free and you don't have to register to watch the lessons.
creativehighschoolmusic.net is a website featuring the Brookline High School Jazz Band. It is designed to encourage collaborative, creative musicianship among students. It contains video and audio of performances and original compositions, as well as video of the Jazz Band's creative process, music lessons, and some podcasts.
