Not just Bee Gees and Disco.
The Eagles, Linda Ronstadt and others blended Rock, Country and Blues. The Ramones, Elvis Costello, Blondie, the Sex Pistols, Devo and others blazed new trails.
Music was only boring if you did not know where to tune your radio.
Blondie is a 70's band not an 80's band and in my opinion the second greatest rock group in the history of music. Beatles being number one.
