Post-rock is a subgenre of rock music that emerged in the 1990s. It's characterized by its use of repetitive melodies, minimal and often abstract lyrics, and a focus on creating atmosphere and mood through instrumental music. One of the most distinctive features of post-rock is its use of dynamics, with songs often building to an intense climax before easing back into a quieter section. The Hollow font is a popular choice for post-rock album artwork as it visually captures the moody, atmospheric feel of the genre with its thin, elongated and minimalistic lettering design.
