[Margaret Pilkington]

If you listen carefully to the artists I have mentioned you will see(or hear perhaps is a better word) where your fave band got some of their musical background from.
Musicians are influenced by the music they have listened to in the past......and all music evolves.
When I was young(which is a long time ago) I listened to Jimmi Hendrix....and Kiss...not so much Led Zeppelin......but I can't say I really ever liked it that much. I listened to it because it was around. I still listen to all kinds of music...but I have to agree with one thing you said...much of the modern stuff is rubbish.
