JAMCON '84 was the first volume in the Over the Edge series, which distills portions of Negativland's radio program Over the Edge, broadcast on KPFA. This album was edited together from at least three different broadcasts recorded between January and July 1985.

The first program, "JAMCON '84," consists of Tracks 1 - 5, and is presented as a radio documentary regarding a convention of Jammers, with commentary on jamming and the culture surrounding it. The second program, "Negativland's 4th of July Stockholders' Picnic," is composed of Tracks 6 & 7, and is presented as a stockholders meeting for people invested in the corporate entity that is Negativland, with updates and reports regarding their recent projects. The last program - and Track 8 of the disc - is "Body English," and is presented as live coverage of President Regan's second inaugural address.

Originally released in 1985 by SST Records on cassette only, it was re-released in 1994 by Negativland's own label, Seeland Records, as a CD with additional tracks featuring the two additional programs. The original Cassette Release contained the "JAMCON '84" program on Side A, and a program called "The Starting Line with Dick Goodbody" on Side B. "The Starting Line" Program appears on Over the Edge Vol. 1½.
