The best parts of the show were definitely the instrumental ones. Whether you care for the music or not, Flea, Frusciante, and Smith are great at their craft, so it's a joy to watch. Not that that makes it worth a small fortune to attend, but sine you're in it already, just enjoy.
I never really connected with The Strokes. They seem like they're too cool to care. And I dislike the lack or any harmonies. It all sort of bores me.
