“Iris” by the Goo Goo Dolls is one of the most iconic alternative rock ballads of the 90s, a song that began as a piece written for a film and ended up becoming something far bigger than a soundtrack, far bigger than a hit single, far bigger even than the phase of the band that gave birth to it. It was written by John Rzeznik for the 1998 film City Of Angels, and inside it carries a peculiar tension between the romantic, the metaphysical, the cinematic, and the deeply human.
