The concert captured here was a very special event. It was the reunion of Van der Graaf Generator.

Vanilla Fudge might be one of the strangest but also coolest bands to come out of the 1960s. Really, progressive rock didn't exist yet, but their sound was such a part of the kind of the thing that would become prog. 

In 2016 there was a concert held as a tribute to Keith Emerson. This amazing package captures that concert.

I reviewed a CD set with a similar cover and title in this issue of Music Street Journal.
