Wipers were a punk rock group formed in Portland, Oregon, United States in 1977 by guitarist Greg Sage, drummer Sam Henry and bassist Dave Koupal. Perhaps best known for the iconic early 80s album Is This Real?, Wipers were one of the earliest American purveyors of the genre, and the group's tight song structure and use of heavy distortion has been hailed as extremely influential by numerous critics and musicians (including Nirvana, who covered several of their songs)
