Great ILM thread which has just been revived:

When You First Heard Your Favourite Record...: "...when was it? ...how old were you? ...where were you? ...who were you with? ...what did you think? ...what did you do or say? "

My answer (I cheated concerning the one record) was and still is:

keith jarrett - sun bear concerts ...when? around 1980 ...age? 17 ...where? on my loudspeakers at home ...who with? me and keith jarrett's groaning ...what did you think? how can one guy on a piano make such intense life-transcending music? ...what did you do or say? i turned the record, put on the next, turned it, put on the next... etc. (there are ten records altogether though i don't think i ever listened to all of them in one sitting)

p.s. the answer to "what did you think?" was too short. at first listen i stopped thinking and was blown away. i was enchanted by the melodic beginnings of each concert, suffered through the aggressive, disharmonious free jazz passages and forgot about the world around when the music reached its hypnotic melodic climax. when jarrett melded with his instrument. those improvisational piano concerts are about sex. listening to them is like watching someone having sex with the instrument he plays. and it is not embarrassing like watching people making sex as your ears actually take part. eyes observe, ears receive.
