To answer my own question, YES it's worth picking up this box set. Currently listening to it and The Doors sound the best I've ever heard. Tight, but loose. Jim is right on, band goes in whatever direction they want/need to, and the recording quality is top notch. The variety of songs played in these 4 shows is fantastic too! They hadn't released Morrison Hotel yet, but play a healthy dose of the disc. I see Maggie M'Gill is played at the end of the last show - one of my favorites ever!
