Heavy metal

Heavy metal (or simply metal) is really a most aggressive music genre in the world that was emerged in the late-1960s and the early-1970s in the United Kingdom and the United States, Origins come from blues rock, acid rock and psychedelic rock.

According to sociologist focused on metal subculture. Deena Weinstein, the main rhythm of the very weird music genre is emphatic and has deliberate tensions. Weinstein observes that the most different sound effects available to drummers provide a rhythmic pattern that assumes great complexity. In many of his songs with the main groove is short, from two to three notes, which generally consist of eighth and sixteenth notes. This rhythmic structure is mainly accompanied by various staccatos, made by the rhythm guitarist's palm mute technique.

The main characteristic of a true heaviest rhythm for this genre is the riff that creates the thematic hook of a song and a instrumental

To this day, there is no precise consensus defining which was the first heavy metal band that some mentioned Led Zeppelin and Deep Purple, while others left that place exclusively to Black Sabbath.5 At the same time, at the end of In the 1960s and early 1970s, many bands emerged that, although they did not have the medical impact of them, were also a contribution to the birth of the genre such as UFO, Blue Cheer, Wishbone Ash, Budgie and Blue Öyster Cult, among others. Subsequently, groups such as Scorpions, Rainbow, Judas Priest emerged, the latter introduced the combination of the double bass drum with fast rhythms in sixteenth note of bass and guitar, and eliminated the latest influences of blues, and Motörhead, who included some elements of punk rock, giving it a new emphasis on aggressiveness and speed. In the second half of the seventies and in the midst of the rise of garage rock, the New wave of British heavy metal the was led by Iron Maiden, Saxon and Def Leppard, which gave a new value to the genre resulting in the birth of a made later own subculture.

Until today there is no clear consensus on the part of the critics, to define which was the first heavy metal band. Many of the American critics give their support to Led Zeppelin, while the British commentators give credit to Black Sabbath and Deep Purple. Also and in other cases, Iron Butterfly, Steppenwolf, Vanilla Fudge or Blue Cheer are named as the pioneers of the genre.69 In what they do coincide is that in 1968 the sound that would be called heavy metal began to be created. In January of that year the Americans Blue Cheer released their single "Summertime Blues" —cover by Eddie Cochran — which was taken from his debut album Vincebus Eruptum and is considered the first record of true heavy metal.70 In the same month, Steppenwolf He debuted with his self-titled album, which included the single "Born to Be Wild" which refers to motorcycles by the term "heavy metal thunder." In June, Iron Butterfly released the album In-A-Gadda-Da-Vida, which contained the hit of the same name and was also nominated as one of the first recordings of the genre.
