Psychologist dissects Pink Floyd's 'Dark Side of the Moon'

As a retired analytically trained psychiatrist, addictionist,  the analysis of someone’s work is often more about projection of one’s own conflicts into the music, not really dealing with the artist unless of course one has done a thorough examination in the proper setting.  
Having said that, my favorite “analysis” is Hotel California by the Eagles.  But, if you have never shot up an opiate, you really are not in a position to guess.  There is a lot of great music, and some of the greatest was created while using mood altering drugs.

Interesting discussion, but for most folks who use mood altering chemicals, alcohol or other, and this becomes compulsive, they have the disease of addiction.  Many great musicians die of their disease.  I was given the gift of sobriety over 35 years ago. Thank you for the topic.
