Among the gifts I received for my 9th birthday in 1986 were (1) An AM/FM radio Walkman (replete with the classic orange-padded on-ear headphones), and (2) a plastic kite with an eagle on it.
The following day, I walked over to the park nearest our house, stood in the middle of an open sports field, tuned my Walkman to the relatively new Australian rock music station EON-FM, and launched my eagle kite.
Fairly soon, as I stood there proudly flying my kite on what was a solidly windy day, the radio playlist transitioned into the intro to Money for Nothing by Dire Straits.
To this day, I can still feel the visceral sensation of the buildup of that intro and the sound explosion of that opening guitar riff, and in that moment I knew what rock'n'roll music was all about.
I sometimes think back to that just-turned-9-years-old kid in the middle of that field, flying that kite and having his mind blown by rock'n'roll blasted through his brand new Walkman, and think "you're doin OK kid."
