I have noticed that the majority of my music/concert dvds (I have 28 of them at the moment) have ever no extras, or very little extras. What sort of extras should music/concert dvds have? Some of the extras I've seen include Photos/discography - I don't find these very interesting but can be informative if you don't know much about the artist. Documentary - I find it very annoying when these are placed throughout the concert. One of my dvds (Travis - live in Glasgow) have a selection for playing the concert and documentary separately. I think the documentary should be kept separate. Concert rehearsal - The Diana Krall dvd has a rehearsal 'extra' on it. Very interesting, especially if they make mistakes, do different versions, play around with it etc Multi-angle views - I am not really a huge fan of this. I trust the director to pick the best view for me. I was disappointed that the U2 - live in Boston dvd had an entire dvd devoted to multi-angles. I have not used this feature at all and would have preferred to save $10 or so and just bought the first dvd with the concert on it. Single videos - Interesting to see. That's about all the extra's I've seen on my dvds. Any thoughts about what you have seen or would like to see?
