As everyone else, I was a fan of Pink Floyd in the sixties.
I had to realize that the use of samples has its rules, too.
A concert is a concert is a concert is a concert. An album is an album is an album is an album. Musically, both have nothing in common.
Psy Free was a trio consisting of guitar, organ and drums. I was the drummer. We did what the name suggests: psychedelic, free music.
Most of today's music is done electronically.
As always in a musical collaboration: One has to like each other. As simple as that.
