Progressive rock music & Hip Hop?

In first place, what ELP does is not sampling, you can call it cover if you want, but musicians playing instruments is not the same as a guy with a recorder adding some basic percussion patterns to the music created and performed by others

In second place, I always wonder why people feel free to come to a Prog site ad say phrases like ELP is pompous crap or Rick Wakeman made that infamous Arthur on Ice, or even worst "All retro Prog is crap", and nobody says a word.

But if in the same Prog site somebody says that he/she doesn't like Rap or Hip Hop, we are middle age ignorant who don't accept that music has to change.

Yes, I'm middle age, but for me sampling is not making music,, it's stealing what real musicians did (As far as I know is very common not to pay royalties), but covers are a valid form of music, just listen guys like Manfred Mann with the Earth Band making a cover of "Blinded by the Light" by Bruce Springsteen (After paying royalties), they create a new, different song, which IMO is much better than the original.

Guys like Emerson had enough respect to go to Ginastera's house to play his Tocatta version before him and received the blessing of the composer who found the track amazing, before even daring to release Brain Salad Surgery,.

There's a huge difference, but at the end, we are free to like what we want and dislike what we want too, accept it.
