Well I hope you realise that CM have only one album thus far, which was undoubtedly a masterpiece and hailed by critics all over the world. So it wouldn't surprise me if they became standard-bearers of their generation.
And yes, comparing Adagio to the likes of Mozart is of course absurd, but this wasn't what I was doing. If you are actually aware of any of Mozart's piano concertos and have heard "Next Profundis" by Adagio, for example, then you should understand what I meant. Adagio take many motifs and ideas from Mozart (to name one composer) and adapt it to the rock genre in a remarkable way.
