there is a lot of good rock/hard rock music out there...but, for one to discount LZ or Beatles, even the Doors to a small degree...is fooling themselves.
Half of the 80's rock is influenced by LZ and Beatles (later years)
Pink Floyd...a whole different animal (pun intended)...if one doesn't enjoy the music of Gilmore/Waters & Co...that's OK...but the back story is one every rock music enthusiast should know. It is very deep & intriguing.
