Jag Panzer's fifth studio album, 2000's "Thane to the Throne," is a concept album based on Shakespeare's "MacBeth." It includes dialogue from the play and features several classically-influenced instrumentals to keep the medieval mood.
The band decided to use the name "Jag Panzer" after they saw a picture of a German WWII tank, "Jagdpanzer", but it was hard for them to pronounce it correctly so they dropped the D and left it Jag Panzer, pronouncing it "Jag" like in "jaguar" rather than "Yag" (meaning the band's pronunciation is not correct German).
