Jon Nelson is a sound collage artist and hosts the program Some Assembly Required. He also produces Radio Retrofit as a series of creative fabrications, focusing on the art of personality driven radio, as represented by various fictional broadcasters, known from film and television. As an artist, he "mashes music and found sound — from old movies, laugh tracks, the news — to make what he calls the audio dreamscape of the media age." Nelson has been championing the genre of collage music since 1999; Some Assembly Required and Radio Retrofit are heard on the Sheena's Jungle Room stream, at WFMU.
