It's excellent stuff, representative of how awesome Fish was at that time. There's not much to be said really, it's what you'd expect, which is official soundboard recordings from 3 different tours. I'd have preferred a little less of Misplaced Childhood and perhaps some early classics like Cinderella Search and Grendel, but overall it's a great boxset.
There's a new boxset available on Fish's site also, "The Early Stages 1982-1987 The Official Bootlegs",looks pretty awesome. If you're like me, I never get enough of Fish-era Marillion and while Hogarth-era is cool, it never fully quench the thirst.
