On the invitation of Yoshitaka Mouri Knut gave a short lecture via Skype and streamed a live radio feedback performance to the Media Ecology of Radio symposium hosted at YCAM, Japan.

Every autumn thousands of wine cellars in the Mosel valley, Germany’s premier wine growing region, turn into magnificent sound installations. Freshly pressed grape juice starts fermenting in barrels and the escaping gas bubbles through glass u-pipes, each barrel at its own speed. Mobile Radio set up seven microphones in the wine cellar of bio-dynamic winemakers Rudolf & Rita Trossen to capture and broadcast live these fermentation sounds, documenting the work of yeast turning juice into wine over a period of 17 hours. The following edit is a recording of the activity in the cellar during the midnight hour on the 5th November 2013.

Many radio stations from the Radia Network broadcast the sounds live through the night (Radio Panik, Radio Zero, free109point9/WGXC, Kanal 103, Radio Campus, Radio Corax, Reboot.fm, Soundart Radio) or as an edit later on (Radio x, Orange 94.0, Resonance104.4fm, Radio One 91FM, Närradio). Even state public radio and television in Germany (SWR1, SWR4 and SWR TV) reported on what they dubbed the ‘bubble symphony’.
A special sacrifice was made by the fruit flies who added their sparks to the soundscape by visting the fly zapper.

After our productive workshop at Konsthall C in May we returned with the idea to create a 24 hour radio art festival on two FM frequencies. Called Dubbelradio, it was probably the first such festival in the world.
The four-channel audio works that were performed and broadcast are hard to document, so we have made a video to show the scope of the project. Click here to watch it in HD. Listening will be greatly enhanced on headphones or decent speakers.

As guest curator and contributor to the Addicted2Random festival of Radio Corax, Knut assembled an international group to produce Imaginary Radio Band No. 1 for the opening of the proceedings at the Händelhaus. The musicians performing live on stage were:
Andre Damião (BR), computer, voice
Børre Mølstad (NO), tuba, voice
Xentos ‘Fray’ Bentos (UK), guitar, voice
Knut Aufermann (DE), electronics, voice
Sarah Washington (UK), electronics, voice
With additional voices by Helen Hahmann and Ralf Wendt
The idea was to produce an acoustic journey through an uncharted band on the radio dial, jumping from station to station. We were lucky enough to work with the museum custodian Christiane Barth, who allowed us to perform on the organ built by Johann Gottlieb Mauer in 1770. The recorded version below is a special reworking of the live recordings for the Radia network by Xentos.

Other events of this wildly diverse and beautiful festival included a duo of Tetsuo Kogawa (on AM transmitters via live-stream from Tokyo) and Knut, a rare DJ set by the elusive Johnny Head-in-Air and the introduction of two people who should have already met decades ago…

We were invited to the annual meeting of the EBU Ars Acustica expert group hosted at the WDR to present our work Mobile Radio BSP from the 30th São Paulo Bienal and to give a talk on the Radia Network which included a sneak preview of the Radia Relay web channel.
