Honestly, I haven't listened to all the disks that much. There are some tracks with a sax player that don't work well. But like any group of live tracks, some are better than others. Let's just say the original album wasn't wrong.
But I like the idea of hearing complete shows, as opposed to a 'best of' from multiple shows. The most successful so far is Jimi Hendrix, "Songs For Groovy Children" (The Fillmore East Concerts). A real tour de force!
