Post-prepared Piano Animated Sequence

I put together this animated sequence of the media from Post-prepared Piano to illustrate the relationships between the spectral analysis, the mapping with nails and twine, and the music from the piece. Thanks to Photosounder developer Michel Rouzic for suggesting that I make a video combining the sound and imagery after seeing the documentation I posted a few days ago.

Post-prepared Piano by John Keston and Piotr Szyhalski

Piotr Szyhalski and I have just finished installing a piece titled, Post-prepared Piano, in the Burnet Gallery at Le Méridien Chambers, Minneapolis. Our installation is part of a show called Interactions and features the work of select MCAD MFA students in collaboration with their mentors. Our piece consists of several components. The first part is a 14′ wide and 17″ tall inkjet print of spectral analysis from a short piano composition that I performed and recorded using my custom built, binaural head microphone (otherwise known as Vincent).

Below the print is an installation that Szyhalski constructed from tarpaper, nails, and one continuous piece of twine. This handmade mapping of the spectral analysis was then photographed and converted back into sound using Michel Rouzic’s excellent application, Photosounder. Thirdly, we installed an iPad with headphones that allows the visitors to hear the original recording, the nails and string version, and a combination of the two layered on top of one another (visit the tablet optimized webapp). The show opens today and runs through February 24, 2013 with an artist’s reception on January 31 from 6pm to 9pm. Read on for more details, photos and sounds. Continue reading

DKO at FRANK Part 2: Everyday Music (2012)

This is an excerpt from a performance by DKO from the MCAD MFA open studio night on December 7, 2012 as discussed in the post Live Binaural Recording of DKO with Oliver Grudem. The document features Oliver Grudem (not shown) who produced the audiovisual score in real-time. The video and sound coming from the LED display and loud speaker below it was broadcast into the performance space as Oliver walked around the Minneapolis Uptown area during a snow storm. The visuals and sound from his walk provided a “score” for us to respond to as we improvised. Oliver was also able to hear our musical reactions to the audiovisual score as he was broadcasting and respond accordingly.

The piece was recorded with my custom built binaural head microphone to capture the sound localization of the performance space. NOTE: It is necessary to wear high quality headphones to experience the binaural effect. The spatial properties of studio monitors are also acceptable but will not produce the same localization of the sound sources. Thanks goes out to Eric Dowell for shooting video of the one hour long performance. I am working on editing a shorter version to briefly summarize the essence of the piece. This 13 minute video is a more in depth snapshot of what the performance entailed.

Live Binaural Recording of DKO with Oliver Grudem

On Friday, December 7, 2012 the MCAD MFA program had its yearly open studio night. Last year it was called SHOW + TELL, but this time we titled it FRANK. There was some amazing work up all over our Whittier studio spaces. I contributed by directing a performance featuring my trio DKO and MCAD alum, Oliver Grudem, who provided a real-time audiovisual score for the ensemble to “read”. This relates to my thesis research in progress, but in brief the audiovisual content was broadcast over a mobile network as Oliver traversed around the city sending us what he saw and heard as it happened.
