First song to "Blow You Away"...

Rockadanny, pick up Steppenwolf "live at the matrix" on Dunhill. It has a 20+ minute version on side 2 of The Pusher that is killer.
rlwaignwright,pick up Maximum Darkness by Mann. It is a great live offering with John Cippolina that is sure to please.

Another one falling prey to Led Zep, in my case "Immigrant Song". I vividly recall being in the garden on a freezing cold night (interested in astronomy, nothing else) when it burst out from somewhere in the neigbourhood. I didn't know who or what it was, just stood there mesmerized, emotions rippling down my spine. Weird enough, several months later at school the art teacher - knowing how to keep his audience interested - did a music quiz and, finally, there it was again! Yep, a school teacher taught me Led Zeppelin.

Shortly thereafter, major blows were to follow
Yes, "Heart of the Sunrise" (actually, the album "Fragile" altered my state of mind for all times, I guess)
Pink Floyd, "Careful with that Axe Eugene"
Japan, "Adolescent Sex"
Genesis, "The Knife"
Jackson Heights, "Bump and Grind"
... with many more to come until this day.

Qdrone - Awesome! Had no idea there was a live version. THANKS!! Take a magic carpet ride on me.

I was driving down I-65 today when Dylan's "Rainy Day Women #12 & 35" came on the radio. It took me back to 1965 or 66 when I was riding home from the store with Mom and "Like a Rolling Stone" came on the radio. We got home before the song ended so I ran into the house to turn the radio so I could catch the end of the song. Yeah, that was probably the first. I was maybe 12 years old.

I've got two tunes that send me to a another zone. The End by Doors and Logos By Tangerine Dream. There are some great song listed in this thread. I am going to made a play list of some to them and just float for an hour or so this weekend. Thanks all.
