Purling Hiss has been played on NTS shows including Kickin Pigeon's Galactic Bounce, with Mercury Retrograde first played on 27 May 2014.

Purling Hiss is the rock music project of American multi-instrumentalist Mike Polizze. Based in Philadelphia, the project was named so because of its heavy use of distortion and white noise. Originally conceived for his own personal amusement and desire to experiment, Polizze eventually self-released Purling Hiss (2009) and began touring with a live band.
