Unsung: The Best of Helmet (1991–1997) is a compilation album of Helmet in its original form, consisting of vocalist/guitarist Page Hamilton, bassist Henry Bogdan, drummer John Stanier, and guitarists Peter Mengede (1989–1993) and Rob Echeverria (1994–1996). It was released in early 2004 in a run-up to the much-anticipated new Helmet album to be released later that year. The title states the years 1991–1997, presumably because 1991 is the year that Interscope rereleased Strap It On; however, it was first released in 1990 on Amphetamine Reptile Records.
