Identify the origins of rock-and-roll music, listing which musical genres it blends together, and name a person who was an important figure in its early development.

It originated in the 1950's in America, and it later on developed into a range of different styles in the1960'sin the united states and the united kingdom. By the late 1960'sit was referred to as the "golden age " or the "classic rock period. a very important figure at that time was Elvis Presley, he was a big thing and he still is, hope this helps :)

Good patients tbh with you
