Performance for Christmas calendar project in Gothenburg Sweden on Dec 9 07. I accompanied Oscar Ramos as he played a window with a speaker and contact mic using feedback through an amplification system.  The performance lasted about 15 minutes and was viewed from the street below.

Description from oramos.org:

Project shown at the bellmanlarssonlindstromnord kalendar projekt. It was a sound installation /performance that worked with the properties of audio feedback. For that night, a simple contact microphone was taped to a window looking to the street. The sound picked up by the microphone, was played trough a speaker that was placed against the glass of the same window. This created an audio feedback that was manipulated and altered by the movement and vibrations of the speaker while i moved and smashed it through all the window. (Dan Wilcox had to take care of the audio feedback running through the P.A and mixerboard)
