I'm a member of a music sharing site and I was blown away yesterday listening to a few 70's songs that are now playing in my head. I've heard them plenty of times when I was younger, but back then I wasn't so aware of what amazing geniuses these musicians are/were.
Emerson Lake & Palmer - "From the Beginning"
Traffic - "The Low Spark of High-Heeled Boys"
Steely Dan - "Black Cow".
These rock & jazz fusion songs are mesmerizing, they take your mind to a beautiful place.
