Green Day

Green Day is a US rock band formed in 1989 that blends punk rock and pop punk, pairing fast, power-chord-driven guitar work and brisk tempos with catchy, hook-focused songwriting. Their arrangements typically emphasize electric guitar, bass, and drums with direct vocal melodies, and their lyrics range from personal and youthful themes to broader political and social commentary. Emerging from the California punk scene, they are often associated with bringing a punk-derived sound into wider rock audiences.
