Power pop is a musical genre that emerged in the late 1960s as a fusion of British Invasion-era rock and American pop and rock music. Characterized by strong melodies, clear vocals, and catchy, guitar-based hooks, it is often described as a more radio-friendly version of hard rock. Notable bands in the genre include The Raspberries, Cheap Trick, and Big Star, whose album "#1 Record" is often considered a seminal work in power pop. Despite its lack of mainstream success, power pop has had a significant influence on later genres such as pop punk and indie rock.
