Rock And Roll Jesus

Rock music is a genre of popular music that developed during and after the 1960s, particularly in the United Kingdom and the United States. It has... its roots in 1940s and 1950s rock and roll, itself heavily influenced by rhythm and blues and country music. Rock music also drew strongly on a number of other genres such as blues and folk, and incorporated influences from jazz, classical and other musical sources. Musically, rock has centred around the electric guitar, usually as part of a rock group with bass guitar and drums. Typically, rock is song-based music with a 4/4 beat utilizing a verse-chorus form, but the genre has become extremely diverse and common musical characteristics are difficult to define. Like pop music, lyrics often stress romantic love but also address a wide variety of other themes that are frequently social or political in emphasis. The dominance of rock by white, male musicians has been seen as one of the key factors shaping the themes explored in rock music. Rock places a higher degree of emphasis on musicianship, live performance, and an ideology of authenticity than pop music.

Jazz is a musical style that originated at the beginning of the 20th century in African American communities in the Southern United States. It was... born out of a mix of African and European music traditions. From its early development until the present, jazz has incorporated music from 19th and 20th century American popular music. Its West African pedigree is evident in its use of blue notes, improvisation, polyrhythms, syncopation, and the swung note. As the music has developed and spread around the world it has drawn on many different national, regional and local musical cultures giving rise, since its early 20th century American beginnings, to many distinctive styles. . Among these styles are New Orleans jazz, dating from the early 1910s, big band swing and Kansas City jazz from the 1930s, and on through bebop from the mid-1940s to cool jazz, modal, hard bop, free jazz, fusion and Latin jazz in various forms. Late in the century it was influencing significant strains of new forms like electronic dance and rap. In a 1988 interview, trombonist J.J. Johnson said, "Jazz is restless. It won't stay put and it never will".
