Rock music originated in the 1950s in the US and has since developed numerous subgenres. It is typically performed with guitars, bass and drums and accompanied by lyrics. In the late 1960s/early 1970s, rock combined with other genres like folk, blues and jazz to influence subgenres such as soft rock, hard rock, and punk rock. One popular subgenre is alternative rock, which emerged from indie music in the 1980s and became widely popular in the 1990s. Rock is now associated with rebellion, aggression and stereotypical dark styles.
