Re-watched this strange mystery/thriller the other day...
Blow-Up (1966)
A young, sucessful photographer takes some spur–of–the–moment outdoor photos in a park and notices something suspicious while developing the pictures. There's a scene featuring a brief appearance by 'The Yardbirds' playing in a club with both Jeff Beck and Jimmy Page on the stage together. The film also includes a subtle film score by jazz pianist Herbie Hancock.
