Chicago Reader review:
'Michelangelo Antonioni's sexy art-house hit of 1966, which played a substantial role in putting “swinging London” on the map, follows a day in the life of a young fashion photographer (David Hemmings) who discovers, after blowing up his photos of a couple glimpsed in a park, that he may have inadvertently uncovered a murder. Part erotic thriller (with significant glamorous roles played by Vanessa Redgrave, Sarah Miles, Verushka, and Jane Birkin), part exotic travelogue (featuring a Yardbirds concert, antiwar demonstrations, street mimes, one exuberant orgy, and a certain amount of pot), this is so ravishing to look at (the colors all seem newly minted) and pleasurable to follow (the enigmas are usually more teasing than worrying) that you're likely to excuse the metaphysical pretensions—which become prevalent only at the very end—and go with the 60s flow, just as the original audiences did'
Here (and above) is the trailer. Here is the famous Yardbirds scene.
