The band say: "This is a four-volume live series we've put together from a time when technology was going through some growing pains and some formats just didn't last very long. Fast forward a few grey hairs down the road and Roger has cleaned them up a bit."

Drummer Vinnie Fiorello adds: "None of these recordings are doctored in any way. We wanted to be archivists of a moment in time - not surgically reconstruct the recording after the fact.
