Era as in album or album span... live albums almost always cover a bands entire career with emphasis on popular and recent/current material.
I'm partial to Burnt Offerings/Dark Saga era. BTW, if you have the original cover to thier first album, I know several people looking for it. Or ebay it for good money.
You're a fan of Demons and Wizards I'm assuming? Do they have any new material coming out? Their first (only?) album was godly. They only had a fill-in studio drummer, but he fit in well. I wish they took that project further.
And am I the only one who thinks the vocals are way to low in the mix on the Horror Show album? Maybe it's just me. My studio speakers aren't working anymore, so I have to resort to listening to music on a standard commercial stereo. Uuug.
