notably Bruce Springsteen and John Mellencamp, although their works have become more personal and experimental and no longer fit easily into a single genre. Newer artists whose music would perhaps have been labelled heartland rock had it been released in the 1970s or 1980s, such as Missouri's Bottle Rockets and Illinois' Uncle Tupelo, found themselves labeled alt-country. Emergence of alternative rock The term alternative rock was coined in the early 1980s to describe rock artists who did not fit into the mainstream genres of the time. Bands dubbed "alternative" had no unified style, but were all seen as distinct from mainstream music. Alternative bands were linked by their collective debt to punk rock, through hardcore, New Wave or the post-punk movements. Important bands of the 1980s alternative movement in the US included R.E.M., Hüsker Dü, Jane's Addiction, Sonic Youth and the Pixies. Artists were largely confined to independent record labels, building an extensive underground music scene based on college radio, fanzines, touring, and word-of-mouth. Few of these bands, with the exception of R.E.M., achieved mainstream success, but despite a lack of spectacular album sales, they exerted a considerable influence on the generation of musicians who came of age in the 80s and ended up breaking through to mainstream success in the 1990s. Styles of alternative rock in the U.S. during the 1980s included jangle pop, associated with the early recordings of R.E.M., which incorporated the ringing guitars of mid-1960s pop and rock, and college rock, used to describe alternative bands that began in the college circuit and college radio, including acts such as 10,000 Maniacs and The Feelies. Alternative goes mainstream (the 1990s) Grunge By the early 1990s, rock was dominated by commercialized and highly produced pop, rock, and "hair metal" artists, while MTV had arrived and promoted a focus on image and style. Disaffected by this trend, in the mid-1980s, bands in Washington state (particularly in the Seattle area) formed a new style of rock which sharply contrasted with the mainstream music of the time. The developing genre came to be known as "grunge", a term descriptive of the dirty sound of the music and the unkempt appearance of most musicians, who actively rebelled against the over-groomed images of popular artists. Grunge fused elements of hardcore punk and heavy metal into a single sound, and made heavy use of guitar distortion, fuzz and feedback. The lyrics were typically apathetic
