A style of rock characterized by a fast tempo, melodic vocals, and "juvenile" subject matter (although some later pop punk delves into deeper lyrical topics). The style was formed in the late 80's when bands began combining an early punk guitar style and lyrics with cleaner vocals, two and three part harmonies, and prominent hooks. This style is much more melodic, but still high energy and sometimes moshable. Depending on the subgenre, bands can exhibit varying degrees of hardcore punk
, and post-hardcore
influences as well. Pop punk bands such as Green Day and Blink-182 went on to develop more alternative influenced sounds with their later albums, while bands like All Time Low nearly abandoned the punk aspect of the music, instead going for a more pop-based, radio-friendly sound.
