During the late '80s and early '90s, lo fidelity became not only a description of the recording quality of a particular album, but it also became a genre onto itself. Throughout rock & roll's history, recordings were made cheaply and quickly, often on substandard equipment. In that sense, the earliest rock & roll records, most of the garage rock of the '60s, and much of the punk rock of the late '70s could be tagged as Lo-Fi. However, the term came to refer to a breed of underground indie rockers that recorded their material at home on four-track machines. Most of this music grew out of the American underground of the '80s, including bands like R.E.M., as well as a handful of British post-punk bands and New Zealand bands like the Chills and the Clean.
