stub wroteQueen- a Night at the OperaThis one's a classic without a doubt.
It is.
Though it has it's share of what some would consider to be filler (an all-too-common affliction for that era), whilst others will say it is merely variety...
Aerosmith - Rocks is another album I would deem a classic, though no filler on this one; lean, hungry (in fact it is downright gaunt) and as dirty as a jailhouse syringe from start to finish... well except maybe Home Tonight, but even that's not bad as far as ballads go.
