Here you have it everyone: The world's first instrument made from a functioning posterior. 

How does one truly assess the value of innovation? Is it defined by how many of us productively use a particular tool in our own lives? Or does it take years to quantify the impact of a given movement?

We ask because the Denmark-based headphone company AIAIAI recently put out an advertisement titled “Real Booty Music” – music made by the ass, for the ass. Is this a new revolution in the form of fanny?

To achieve the captivating feat, AIAIAI employed the help of dancer “Twerk Queen” Louise, the Dutch tech and design company OWOW and Portugal-based DJ/producer Brako. The company calls the video a “a collaborative project where all parties play an equal part in realizing the project” and maintain the clip is merely for experimentation and to get the name of their headphones out to the masses (read: advertisement).

Twerk Queen’s inventive asstrument* is a series of sensors taped directly to the hiney. When juggled accordingly the momentum of the fluff-cheeks are then transferred to sound. The resulting effect is heard in Brako and JSTSR’s song “Cascavel” — an interesting fusion of world tones and dance inducing repetitive buildups.

"The overall idea behind the project was to provide AIAIAI headphone users and other music lovers with new music,” says AIAIAI. “Moreover, we wanted to do this in an unusual way, which brought about music made by the booty—for the booty. The project explores the rich heritage of bass-driven club culture, where dancing and booty shaking are integral elements. We want to see if it's possible to change the perception of twerking through placing it in a technology-driven, creative context and letting the dance 'do the talking.'"
