Query: great 70's blues-n-rock'n-roll

I HAVE BEEN LISTENING TO ARS SINCE THE MID 70'S. THE EMOTIONS THEIR MUSIC INVOKED IN ME STILL STIRS WHENEVER I AM LUCKY ENOUGH TO HEAR ANY TUNE FROM THIS GREAT CLASSIC ALBUM ON THE AIRWAYS. SADLY THOUGH, TODAYS MAINSTREAM RADIO STATIONS HAVE ALL BUT FORGOTTEN HOW REALLY GOOD THEIR MUSICIANSHIP AND MELODIES WERE, ARE, AND ALWAYS WILL BE.
