Die hard fans who want everything will go out and buy the two, complete concerts from Bright Midnight. If you don't want to spend, then this would be a good pickup. Just keep in mind you're hearing selections, not a complete show.
Of course, when it comes to releasing the same material in various forms as different products, the Doors have few rivals. (The Who come to mind). They release boxsets and then selection discs from boxsets, single and double disc best ofs and greatest hits.
Great music, just decide how much of it you want.
