I HOPE A FEW MORE PEOPLE CAN CONTRIBUTE SOMETHING TO THIS POST ...
... before I say what i have to say on the subject, as after a few returned comments on my perspectives, I suppose the topic will be considered as past it's best before date. Just like anything else, a 'best before' label doesn't mean it's unfit for consumption, but just that you may have liked it a bit more if you didn't leave it so late.
For myself I feel when I hear the word 'psychedelic' Music/art comes to mind first and by music I mean mainstream sixties psychedelic tracks..early Floyd, Hendrix, Beatles ,Stones Satanic its as simple as that for me just the music. By art I talk about album covers and fashion. IMHO hippie shit muddied the waters of Psychedelia.
Just my thoughts
