Filter is an American rock band formed in 1993 in Cleveland, Ohio, by singer Richard Patrick and guitarist and programmer Brian Liesegang. The band was formed when Patrick desired to start his own band after leaving Nine Inch Nails as their touring guitarist. Their debut album, Short Bus (1995) received platinum certification by the Recording Industry Association of America (RIAA), supported by the single "Hey Man Nice Shot." After the album, the band would go through the first of many lineup changes, leaving Patrick as the only consistent member across all releases.

Richard Michael Patrick is an American singer, musician and songwriter. He is the frontman for the rock band Filter and a founding member of the supergroups Army of Anyone and The Damning Well, and has served as a touring guitarist for Nine Inch Nails.
