I love anything to do with the hippie counter culture.  I joke with my dad who grew up In that time that I would of never survived it!  I am all for expanding of the mind but now we are aware of the psychological effects of these drugs...The hard drugs that we lost a lot of these important musicians to.  They truly made an ever lasting imprint on our cultures music.  I agree this should be preserved because it is one of the top albums/bands that were popular at this time.  This music has never seemed to go out of style too, it's still extremely popular in our age today.  I didn't know John Lennon introduced the Beatles to marijuana! What an awesome way to be introduced!
