Filter was formed in Cleveland, Ohio, in 1993 by Richard Patrick, a former touring guitarist for Nine Inch Nails, and guitarist and programmer Brian Liesegang. Over its career, the band has released eight studio albums, including Short Bus (1995), which features the hit single “Hey Man, Nice Shot,” and Title of Record (1999), known for the hit “Take a Picture.” Their sound is characterized by a mix of industrial rock and alternative rock, a style that has evolved over the years through multiple lineup changes.

The band has undergone numerous transformations, with more than two dozen musicians contributing to its sound as full-time members, touring musicians, or session players. Richard Patrick remains the sole constant member and creative force behind the band. Filter’s eighth studio album, The Algorithm, was released in 2023, followed by The Algorithm: Ultra Edition in 2025. Filter continued touring throughout 2026, with another studio album in development.

Filter’s longevity can be attributed to its ability to adapt and incorporate different musical influences. Their albums have charted globally, and tracks such as “Hey Man, Nice Shot” and “Take a Picture” have achieved lasting recognition. Their body of work reflects a deep engagement with themes of personal struggle, introspection, and societal commentary.
