Information:  - Rock music is a genre of popular music that originated as "rock and roll" in the United States in the 1950s, and developed into a range of different styles in the 1960s and later, particularly in the United Kingdom and the United States. It has its roots in 1940s' and 1950s' rock and roll, itself heavily influenced by blues, rhythm and blues and country music. Rock music also drew strongly on a number of other genres such as electric blues and folk, and incorporated influences from jazz, classical and other musical sources.  - No Policy is the only studio release by the American hardcore punk band State of Alert, the first band to be fronted by Henry Rollins. It was released on 7-inch vinyl in March 1981 through Dischord Records (No. 2). Since Dischord was tied up in releasing Minor Threat's debut EP, the production of "No Policy" was funded entirely by Rollins.  - Dischord Records is a Washington, D.C.-based independent record label specializing in the independent punk rock music of the D.C.-area music scene. The label is co-owned by Ian MacKaye and Jeff Nelson, who founded Dischord in 1980 to release "Minor Disturbance" by The Teen Idles. Along with other independent American labels such as Twin/Tone, Touch and Go Records, and SST Records, Dischord helped to spearhead the nationwide network of underground bands that formed the pre-Nirvana indie-rock scene. These labels presided over the shift from the hardcore punk that then dominated the American underground scene to the more diverse styles of alternative rock that were emerging.  - Straight edge (sometimes abbreviated sXe or signified XXX or X) is a subculture of hardcore punk whose adherents refrain from using alcohol, tobacco and other recreational drugs, in reaction to the excesses of punk subculture. For some, this extends to refraining from engaging in promiscuous sex, following a vegetarian or vegan diet, and/or not using caffeine or prescription drugs. The term "straight edge" was adopted from the 1981 song "Straight Edge" by the hardcore punk band Minor Threat.  - AllMusic (previously known as All Music Guide or AMG) is an online music guide service website. It was launched in 1991 by All Media Guide which later became All Media Network.  - The Teen Idles were an American hardcore punk band formed in Washington, D.C. in September 1979. Consisting of teenagers Nathan Strejcek, Geordie Grindle, Ian MacKaye and Jeff Nelson, the Idles' recorded two demo sessions and the 1980 "Minor Disturbance" EP before they broke up in November 1980. The influential independent record label Dischord Records was originally created with the sole purpose of releasing the Teen Idles 7" record. They were an early landmark in the D.C. hardcore movement, and MacKaye and Nelson would later form the seminal punk outfit Minor Threat.  - Hardcore punk (often abbreviated to hardcore) is a punk rock music genre that originated in the late 1970s. It is generally faster, harder, and more aggressive than other forms of punk rock. Its roots can be traced to earlier punk scenes in San Francisco and Southern California which arose as a reaction against the still predominant hippie cultural climate of the time and was also inspired by New York punk rock and early proto-punk. New York punk had a harder-edged sound than its San Francisco counterpart, featuring anti-art expressions of masculine anger, energy and subversive humor. Hardcore punk generally disavows commercialism, the established music industry and "anything similar to the characteristics of mainstream rock" and often addresses social and political topics.  - State of Alert (often abbreviated to S.O.A.) was an American hardcore punk group formed in Washington, D.C. in October 1980, and disbanded in July 1981. The group was formed after the members' of previous group, The Extorts, lost its vocalist Lyle Preslar and hired Henry Rollins, then known by his birth name Henry Garfield.   - Punk rock (or simply "punk") is a rock music genre that developed in the early to mid 1970s in the United States, United Kingdom, and Australia. Rooted in 1960s garage rock and other forms of what is now known as "proto-punk" music, punk rock bands rejected perceived excesses of mainstream 1970s rock. Punk bands typically use short or fast-paced songs, with hard-edged melodies and singing styles, stripped-down instrumentation, and often political, anti-establishment lyrics. Punk embraces a DIY ethic; many bands self-produce recordings and distribute them through informal channels.  - An electric guitar is a fretted string instrument that uses a pickup to convert the vibration of its stringswhich are typically made of steel, and which occurs when a guitarist strums, plucks or fingerpicks the stringsinto electrical signals. The vibrations of the strings are sensed by a pickup, of which the most common type is the magnetic pickup, which uses the principle of direct electromagnetic induction. The signal generated by an electric guitar is too weak to drive a loudspeaker, so it is plugged into a guitar amplifier before being sent to a loudspeaker, which makes a sound loud enough to hear. The output of an electric guitar is an electric signal, and the signal can easily be altered by electronic circuits to add "color" to the sound or change the sound. Often the signal is modified using effects such as reverb and distortion and "overdrive", with the latter being a key element of the sound of the electric guitar as it is used in blues and rock music.  - Henry Rollins (born Henry Lawrence Garfield; February 13, 1961) is an American musician, actor, writer, television and radio host, and comedian. He hosts a weekly radio show on KCRW, and is a regular columnist for "LA Weekly" and "Rolling Stone Australia".  - The guitar is a musical instrument classified as a string instrument with anywhere from four to 18 strings, usually having six. The sound is projected either acoustically, using a hollow wooden or plastic and wood box (for an acoustic guitar), or through electrical amplifier and a speaker (for an electric guitar). It is typically played by strumming or plucking the strings with the fingers, thumb and/or fingernails of the right hand or with a pick while fretting (or pressing against the frets) the strings with the fingers of the left hand. The guitar is a type of chordophone, traditionally constructed from wood and strung with either gut, nylon or steel strings and distinguished from other chordophones by its construction and tuning. The modern guitar was preceded by the gittern, the vihuela, the four-course Renaissance guitar, and the five-course baroque guitar, all of which contributed to the development of the modern six-string instrument.  - String instruments, stringed instruments, or chordophones are musical instruments that produce sound from vibrating strings when the performer plays or sounds the strings in some manner.   - Minor Disturbance is the only studio release by the American hardcore punk band The Teen Idles. It was released in December 1980 through Dischord Records (No. 1). Comprising eight songs, "Minor Disturbance" referenced a number of issues pertinent to the band, from being turned away at local concerts due to their age ("Too Young to Rock") to what they felt was the increasing complacency of many first wave punk bands ("Fleeting Fury"). Upon its release, "Minor Disturbance", Dischord Records' first release, received positive reviews from local fanzines and gained airplay on local radio stations.  - SST Records is an American independent record label formed in 1978 in Long Beach, California by musician Greg Ginn. The company was initially formed in 1966 by Ginn at age 12, as Solid State Tuners, a small business through which he sold electronics equipment. Ginn repurposed the company as a record label to release material by his band Black Flag.  - Southern California, often abbreviated as SoCal, is a geographic and cultural region that generally comprises California's 10 southernmost counties. The region is traditionally described as eight counties, based on demographics and economic ties: Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, and Ventura. The more extensive 10-county definition, which includes Kern and San Luis Obispo counties, is also used based on historical political divisions.
