These two do a very good job talking about this movie. They talk about how the project started, how they got the financing, how they found the original gang after not having seen them for some 20 years, the evolution of the documentary, the editing style and the music. They talk pretty much throughout the movie. They both talk about the music and how important it was. They also yack about how some of the segments were re-edited and shifted around within the movie. It’s very interesting to listen to. You get a real sense of how this movie was made and how it found its voice. You get to learn that, from conception to completion, this documentary only took 6 months. As I said, it’s a very interesting commentary with a lot of information. Anything that couldn’t be said in the movie is said here, as Mr. Peralta talks about the original gang a little, also. It very much adds to the movie, so it’s a very good track.

The above review sums up the commentary nicely. I'd also like to add that the two men talk about how, before the film was edited together, they assembled a trailer to show to all the rock bands that they wanted to use their music in the movie to give them an idea of what it was all about. This is solid track with some good anecdotes, like how they got Sean Penn involved (he was a surfer and a skater and even went to school with some of the Z-Boys), that makes this worth a listen.
