I want to know the answer to the following question:
What sub-genre of hard rock does Def Leppard belong to?
All the background I'm provided with is that "Often categorised with the New Wave of British Heavy Metal, in 1981 Def Leppard released their second album High 'n' Dry, mixing glam-rock with heavy metal, and helping to define the sound of hard rock for the decade.". Is that enough to answer the question?
