One of the first alternative rock bands, R.E.M. was noted for Stipe's particular vocal quality and obscure lyrics, Buck's ringing, arpeggiated guitar style, and Mills' melodic basslines and backing vocals. R.E.M. released its first single—"Radio Free Europe"—in 1981 on the independent record label Hib-Tone. The single was followed by the "Chronic Town" EP in 1982, the band's first release on I.R.S. Records. In 1983, the group released its critically acclaimed debut album, "Murmur", and built its reputation over the next few years through subsequent releases, constant touring, and the support of college radio. Following years of underground success, R.E.M. achieved a mainstream hit in 1987 with the single "The One I Love". The group signed to Warner Bros. Records in 1988, and began to espouse political and environmental concerns while playing large arenas worldwide.

Document 4: Pylon (band): Pylon were an American rock band from Athens, Georgia. The band's danceable sound, a blend of new wave, post-punk, jangle pop, alternative rock and funk rock, influenced the Athens music scene and the 1980s American pop underground. AllMusic wrote that Pylon's "role as elder statesmen of the alternative rock explosion is unassailable".
Document 5: List of rock genres: This is a list of rock music genres consisting of subgenres of popular music that have roots in 1940s' and 1950s' rock and roll, and which developed into a distinct identity as rock music in the 1960s, particularly in the United Kingdom and the United States. By the late 1960s, a number of identifiable rock music subgenres had emerged, including hybrids like blues rock, folk rock, country rock, and jazz-rock fusion, many of which contributed to the development of psychedelic rock influenced by the counter-cultural psychedelic scene. New genres that emerged from this scene included progressive rock, which extended the artistic elements; glam rock, which highlighted showmanship and visual style; and the diverse and enduring major subgenre of heavy metal, which emphasized volume, power, and speed. In the second half of the 1970s, punk rock both intensified and reacted against some of these trends to produce a raw, energetic form of music characterized by overt political and social critiques. Punk was an influence into the 1980s on the subsequent development of other subgenres, including new wave, post-punk and eventually the alternative rock movement. From the 1990s alternative rock began to dominate rock music and break through into the mainstream in the form of grunge, Britpop, and indie rock. Further fusion subgenres have since emerged as well as conscious attempts to revisit rock's history.

This album is the last of Rivermaya with Rico Blanco as the vocalist.
Document 12: La Barranca: La Barranca has been a successful ongoing outfit for over a decade. Based in Mexico City, they are led by guitarist and songwriter José Manuel Aguilera, who previously and concurrently worked with Sangre Azteka, Jaguares, Cecilia Toussaint, Steven Brown/Nine Rain (Tuxedomoon), and more. He has an unusually economical style of playing that concentrates on great rhythms, superb tone, and very melodic solos. After the original lineup—Aguilera, Federico Fong (bass), Alfonso Andre (drums), all of whom were guest members of Jaguares with former Caifanes frontman Saúl Hernández—went its separate ways, a second version of the band included Santa Sabina guitar virtuoso Alex Otaola and the extremely flexible rhythm section of brothers Jose María ("Chema") and Alonso Arreola. The band's sound effortlessly moves from flat out rock to fusion-ish jamming and passes through a kind of Mexican folk influence along the way. Aguilera is a good singer with a talent for finding simple melodies amidst rather complex songs. On "El Fluir" the band decided to record live and to cut back on the keyboard and programmed additions to their music. Surprisingly, the result was not an over-the-top jamfest but rather a very tightly arranged set of songs that hinted at the overwhelming power they could possess in concert. The two guitar interplay between Aguilera and Otaola was highly impressive as they explored all forms of playing together and against one another (with Otaola pulling all sorts of radical sounds out of his guitar). "El Fluir" was their first US release since "Tempestad" in 1998. This edition was further sweetened by the inclusion of a previously unreleased bonus track and a video for the first single "Pare de Sufrir."
