The rival 1960s band that pushed Jethro Tull to be “more original”Even though prog rock is a genre which is pretty impossible to define, Ian Anderson has managed to establish himself as a master of it. Rock bands add on different sections to their music in a bid to take the sound to new heights. There are a few bands that have contributed towards the creation of this genre, but they weren’t actively trying to make prog rock.
