Grunge wasn't just the death of rock n' roll (a genre which was dying anyway-- not even GnR could pull it back up). It was the death of britpop & Madchester, metal, glam rock, shoegazing, pop, and Yngiew Malmsteens career. You should tell your brother that truth be told, rock n' roll sucks.
I couldn't do that, especially seeing as I don't think so. Well, that and he could definitely beat me up (if he wanted to) and I'm sure you, too, if you told him that to his face. You probably wouldn't, though. He'd just stare you down and you'd crawl away. He's a bit intimidating. He might be my younger brother, but he's a full 6'6, with long hair, and looks for all the world like the archetype of Rock and Roll. He probably knows more about music than you could dream of, and has the talent to boot.
The thing is, you're dead wrong. The end of Malmsteen's career? Then how come he's still making music, and still successful, to this very day? The only reason he had a setback then was because of his car accident. He lost the ability to use his arm. Ever wonder why he was so fat for a while? It was the coma he had been in. And for Rock dying... no. Rock never dies, and its continued popularity (hey, GnR still has full crowds, even with only Axl left) is proof of that. What changed was the attitude. The free, party and go-for-it attitude that drove Rock disappeared for more depressing and dim (yes, dim - shadows and grey) in the 90s, so naturally Rock had no fertile ground in that era. And how did pop die? It's still around! Really, I don't think you know what you're talking about. I barely know anything about this, but I seem to know a bit more than you anway.
Oh, by the way, I'm going to see Aerosmith tomorrow so, heh, no, Rock doesn't suck. I might prefer instrumental type of music most of the time, but it's definitely a thousandfold better than what I've ever heard from Grunge. It's got melody, art, and raw power. There's colour and substance there, and by nature Grunge isn't that, and can't be half the music or colour of art that Rock is. Not to mention that it's sheer folly to say of something as wide-ranging as Rock that it sucks. You might not like this band or that, but considering it encompasses things from Aerosmith to the Stones to Led Zeppelin to Van Halen to etc. etc. of such diversity as probably no other musical genre exists, a blanket statement like that is ridiculous.
