There were a few exceptions, namely, some conceptual "anti-records" they released in the late 1980s and early 90s. The first, from 1988, was entitled "Wind Licked Dirt", and consisted of an uncut vinyl LP in a cover packed with a bunch of small pebbles, which are included to "play" the record with. A later edition of this was made with a "CD" (a clear protective disc from a spindle of blank discs), and it is currently available as a "C-0 cassette." The second was entitled "Oxygen is Flammable", and was a broken piece of plastic packaged in a small box. Enclosed were instructions which state that the piece of plastic is a record, and that it's played by pouring water over it. The instructions also call attention to possible similarities between the sounds of water falling and fire rising. The third, "Shear", was a ball of cotton batting packaged in a small box. Wrapped around the contents are instructions on three thin strips of paper, which informs the holder that the cotton batting is a recording, which is played by squeezing. The sounds this "record" gives are described by Larsen as being a "sharp fluffy slightness" and a "thin fluffy pressed". These three releases are, in and of themselves, a kind of performance piece. A self-released 7" single from 1983 worked on the same principle; it consisted of two blank grooves and contained instructions to "complete this record by scratching it...".
