In my opinion BG have released nothing but masterpieces since 1992. Somewhere Far Beyond, IFTOS, NiMe and ANATO.
Their earlier albums are a bit weaker although there are a few kick-ass songs scattered on them (such as Majesty, Valhalla, Lost In The Twilight Hall, Banish From Sanctuary)
by the way, the Tokyo Tales live version of Banish... is awesome! Beats the album version
by far.
