I remember watching Led Zepplin outdoors at the Oakland Collisium while on LSD. They were in the middle of their set, playing" No Quarter " and the haze had burned off and the sun was shining . That was one of my " MORE HEIGHTENED " Listening experiences . I did everything except heroein . But I quit drugs in '89 and stopped drinking in '97. So now I'm 59 and have a long history based on going back over all the music ( if they are still alive ) and being able to rellisten to all the recordings with a clear mind . At home my focus is on music through a very detailed low power tube system . It's at its best in the middle of the night . So looking back , the stimulants , hallucinogens and Marijuana enhanced the live experience . But at home it's been better for me with a clear head . Even back then I preferred watching the African Cichlids in my 200 gallon tank over getting stoned to relax . So I think for me it was the effort into my stereo and listening room that mattered the most . So now when I want to " GET A BUZZ " , I tube roll or go to small venue live shows . So I used to be a Stoner , BUT I WAS AND STILL AM AN AUDIOPHILE . Happy Listening , Mike.
