Claim: AC/DC has dubbed their music as a genre of music.
Evidence: A hard rock/blues rock band , they have also been considered a heavy metal band , although they have always dubbed their music simply `` rock and roll ''.
Rock and roll -LRB- often written as rock & roll or rock 'n' roll -RRB- is a genre of popular music that originated and evolved in the United States during the late 1940s and early 1950s , from African American musical styles such as gospel , jump blues , jazz , boogie woogie , and rhythm and blues , along with country music.
While elements of rock and roll can be heard in blues records from the 1920s and in country records of the 1930s , the genre did not acquire its name until 1954.
