According to the original liner notes, the album "was recorded on a hot pollution alert day during July [1987] in Louisville, Kentucky, and was made at a place called Artist Recording Service.  We recorded 15 songs between 11:00 pm and 5:00 am, half of the time spent trying to fix the wild buzz coming out of Rick's amp.  We finally gave up and decided to make amp buzz the theme of the record."  The album was re-released and expanded in 2003 by Thrill Jockey.
