With only a single entry for this week's "Harmonium" challenge, we draw heavily on the RadioSpiral library this week for a program inspired by glass in many states.

For the “Harmonium” challenge, artists were to take glass sounds (struck, rung, sung, blown, etc.) and make music of the sounds. We only received one brief entry (thank you, Cloudwalk!), but the topic inspired a fascinating show anyway.

We’ll listen to artists’ interpretations of glass in various states — shattered, smooth, stained, still, and much more. We’ll hear the challenge track from Cloudwalk, and then turn to the RadioSpiral archives for works from ʞu¡0ɹʞS, John Koch-Northrup, Bing Satellites, Luna Firma, Max Corbacho, Robert Rich, Tone Ghost Ether, Tony Gerber, Numina, Emerald Adrift, EugeneKha, Michael Brückner, Thom Brennan, Pallid Mask, Jack Hertz, and Altus.
