Quicksand is an American post-hardcore band from New York City, founded in 1990. Their debut self-titled EP was released on followed by two major-label albums, Slip (1993) and Manic Compression (1995). Quicksand's sound has been compared to that of post-hardcore bands Fugazi and Helmet. The band supported their releases with extensive touring but fell short of the mainstream success anticipated by their labels. These factors and internal stress led them to separate first in 1995 and again in 1999 following a failed year-and-a-half reunion. In June 2012, Quicksand reunited for a special one-night performance and since has been playing additional live shows. The band's third album, Interiors, was released on November 10, 2017, and it was followed four years later by their latest album Distant Populations (2021).

Post-hardcore is a punk rock music genre that maintains the aggression and intensity of hardcore punk but emphasizes a greater degree of creative expression. Like the term "post-punk", the term "post-hardcore" has been applied to a broad constellation of groups. Initially taking inspiration from post-punk and noise rock, post-hardcore began in the 1980s with bands like Hüsker Dü and Minutemen. The genre expanded in the 1980s and 1990s with releases by bands from cities that had established hardcore scenes, such as Fugazi from Washington, D.C. as well as groups such as Big Black, Jawbox, Quicksand, and Shellac that stuck closer to post-hardcore's noise rock roots. Dischord Records became a major nexus of post-hardcore during this period.
