Alternative movement (3,3)
I believe the answer is:
new age
'alternative movement' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for new age that I've seen before include "Modern holistic philosophy" , "1980s cultural trend" , "That's very spiritual" , "Modern belief system" , "Of a movement based on alternatives to traditional ideas of Western culture" .)
