It's rather amusing to think that Cream formed over 40 years ago.
They were so revolutionary, just about everything they did left a huge influence on rock bands to come.
Ginger Baker is an insane drummer, and was one of, if not the very first, to use a double bass drum.
Jack Bruce invented and perfected that fade-in bass technique and Eric Clapton...well, when you hear the man rip it out , you know these guys were something special.
Cream were a very good hard rock band that influenced many other hard rock bands.
You can listen to Cream over and over again and never get bored.
