Def Leppard was a glam metal group during the 1980s. They had a couple of great albums such as Pyromania and Hysteria during the 1980s that were a big deal. Unlike most glam metal groups they didn’t really decline during the 1990s. Instead of they tried some interesting, different directions with albums like Slang and stuck with their original 1980s style with albums like Euphoria. They are making good music even today with their Songs From the Sparkle Lounge album, which came out five years ago. The great thing about Def Leppard is that they have been able to change with the times but still maintain their own unique sound and sound just as good after the last couple of decades.
