ADAM is a girl band from the Netherlands, with five singers. They want you to remember them, and their somewhat unusual approach to making a a low budget video is to sing while having orgasms. Took me a moment to figure out that they're sitting on some sort of vibrating device... They're doing quite well in keeping their tune while being very distracted.
And yes, it's a little like the "head shots" Badlanded campaigns, or like Arvika Festival "Orgasm" commercial... The fact that we see these ladies small O-faces is a little like the Nymphomaniac posters. Unlike the szul.com Orgasm viral this won't cost $5 in damages.
Update: Boyband BACKPACKER's parody.
