Def Leppard is re-releasing a digital studio recording of their album 'Hysteria' for two reasons. One, they see it as a great way to celebrate their Vegas residency. Second, it's a part of a larger plan to get bak the rights to their music.
Joe Elliot, the singer, told Classic Rock Magazine that, "We're trying to wrestle back our career and ownership of these songs. They [Universal] own the originals; we're at loggerheads with them over the digital rights. And as long as they're playing silly buggers, we'll just keep recording them again."
Def Leppard is not the only band who's had an issue like this, but they are in a unique position. Elliot told the Hollywood Reporter in another interview that, "[Universal] can't release our back catalog, we're not going to let them put a song on a compilation unless we want it there, and they'll never be able to license. They won't be able to do anything without our permission because that's in our contract."
