Hum is an American alternative rock and post-hardcore band formed in 1989 in Champaign, Illinois; the band performed a mix between both genres obtaining a characteristic heaviness that would define them for the rest of their career (this sound is also known today as Heavy Alternative). The band went through member changes until 1993, finally settling with Matt Talbot (vocals, guitar), Tim Lash (guitar), Jeff Dimpsey (bass) and Bryan St. Pere (drums) until their split in 2000.

The band is best known thanks to the single Stars from the album You'd Prefer An Astronaut, appearing in the tops of several magazines and on various radio stations at the time.

The band was mostly inactive (except for sporadic performances) until reuniting in 2015 for a series of short tours. On June 23, 2020, the band announced and released Inlet by surprise via the internet, their first album of new material in over twenty-two years. On July 1, 2021, it was announced via Instagram that the band's longtime drummer Bryan St. Pere had passed away at the age of 52, prompting the band to cease activities once again.
