I'd be hard pressed to pick a fave out of those ACG LPs, excluding the two pre Ezrin ones, which are eccentric at best, including some prototype songs, like "Reflected"...
I have to include Nightmare in that mix though, probably as I saw the tour - Uwe mentioned the Reed band, which was essentially his band for that tour (Hunter/Wagner/Prakash John - bass/Penti Glan - Drums/ Josef Chirowski - keys)
Wagner started "guesting" from Schools out era...
