Mysterious anonymous collective TQX (TourniquetX)’s debut single “The Day That You Moved On“, is an impassioned song co-written with, and featuring the voice of Sia – the award-winning singer-songwriter who’s worked with everyone from Zero 7 to Beck, Kendrick Lamar to Angel Haze.

With Sia’s soulful tones, plangent piano and a dramatic sweep of drums and guitars, it’s worthy of a spy thriller soundtrack. A haunting song on the raw vulnerability of human attachment, when you view the video, the plot thickens. In a twisted futuristic world, humanity and technology melt together. A surrogate Sia merges with another woman to become the TQX avatar. It’s a virtual creation designed to reframe pop culture and suggest a political, philosophical, and cultural rethink.

As an artist famed for questioning attitudes towards image and marketing by singing live with her back to audiences or with her face obscured, Sia was the perfect candidate to participate in the project,” TQX say. “She’s brought the challenging nature of art into the pop world, which we really like.”

The forthcoming TQX album ‘Global Intimacy‘ features an all-star cast of guest artists, from R&B singer Daniel Merriweather and Gabriel Winterfield of psychedelic dance outfit Jagwar Ma, to New York MC Cormega and players who’ve worked with David Bowie, D’Angelo and Jeff Buckley.
