Music Videos worth watching (and they're free)
YouTube has been a boon for music artists (as well as video artists). Numerous performers and composers have works on YouTube, some videos of just the music, other videos with discussions on the process. I find this particular illuminating when composers get the chance to talk about their works.
However, I came across a real find the other day - Beyond the Score, a collection of videos by the Chicago Symphony Orchestra exploring more than just the music.
