The Dark Side of the Moon has flash - the true flash that comes from the excellence of a superb performance.
The Dark Side of the Moon is a fine album with a textural and conceptual richness that not only invites, but demands involvement. There is a certain grandeur.
Any effects created before 1975 were done with either tape or echo chambers or some kind of acoustic treatment. No magic black boxes!
Folk rock was my real roots. I did a few gigs as a folk artist, in the style of Fairport Convention.
That Beatle euphoria has always been there, and it's hard to be in a room with a Beatle and try to be totally natural. You never shake that off.
