An open call went out to sound artists worldwide for audio art and/or music in any genre, which incorporated the sounds of urban non-human animals and/or the habitats we share. We encouraged the use of the archive of animal vocalizations that are available at the Borror Lab of Bioacoustics at the Ohio State University. The jury was: TradeMark Gunderson, audio artist (aka The Evolution Control Committee), Angelika Nelson, Curator of the Museum of Biological Diversity Borror Laboratory of Bioacoustics, Doo-Sung Yoo, Artist and Adjunct Faculty in the Department of Art at the Ohio State University and Michael Mercil, Professor of Art at the Ohio State University. These are the artists whose works were most creatively manipulated audio files of animal sounds/vocalizations from the urban environment. There were a total of 70 applicants and 19 soundworks were selected, by 18 artists from 9 different countries.
