Please answer the following question: 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. - Letting Go is alternative metal band Earshot 's debut album . '' Get Away '' and '' Not Afraid '' were released as singles and were minor hits with each having their own music video . '' Get Away '' reached # 4 on the U.S. Active Rock Charts and stayed in the top 100 for over 64 weeks . Letting Go reached # 82 on The Billboard 200 . - Alternative metal (also known as alt-metal) is a rock music genre that infuses heavy metal with influences from alternative rock and other genres not normally associated with metal. Alternative metal bands are often characterized by heavily downtuned, mid-paced guitar riffs, a mixture of accessible melodic vocals and harsh vocals and sometimes unconventional sounds within other heavy metal styles. The term has been in use since the 1980s, although it came into prominence in the 1990s. - Alternative rock (also called alternative music, alt-rock or simply alternative) is a genre of rock music that emerged from the independent music underground of the 1980s and became widely popular in the 1990s and 2000s. In this instance, the word "alternative" refers to the genre's distinction from mainstream rock music. The term's original meaning was broader, referring to a generation of musicians unified by their collective debt to either the musical style or simply the independent, D.I.Y. ethos of punk rock, which in the late 1970s laid the groundwork for alternative music. At times, "alternative" has been used as a catch-all description for music from underground rock artists that receives mainstream recognition, or for any music, whether rock or not, that is seen to be descended from punk rock (including some examples of punk itself, as well as new wave, and post-punk). - Earshot is an American hard rock/alternative metal band from Los Angeles, California. The band has released three albums: "Letting Go", "Two", "The Silver Lining", and have most recently announced plans to release their fourth studio album, a 5-song Mini-LP entitled "Aftermath" on April 16, 2015.
