Threshold Shift will be airing it's next episode starting late night on Friday, June 29th and leading into the morning of Saturday, June 30th. It will be a very special re-broadcast of segments from A Different Nature's 2004 Earth Day twelve-hour special. This kicks off a collaborative project between Threshold Shift, A Different Nature, KBOO, and OMSI to celebrate KBOO's history of environmental audio and advocacy. We will have two chances to collaborate with the planetarium this summer and fall to feature surround sound mixes of selected soundscapes and the celestial skies of their recording locations and times. Tune in to Threshold Shift this coming weekend for more information on how to join us for this immersive global experience.
