Unsung: The Best of Helmet (1991–1997)

The compilation was originally scheduled to be released in late 2003, with tentative release dates of September 23, 2003, and then November 4, 2003 being given to the press.[4] When the compilation was first announced on August 22, 2003, it was reported that the band's original lineup would be reuniting for a tour in conjunction with the compilation's release.[5] However, later that month, Hamilton denied reports that Helmet were reuniting.[6] By the time the compilation was eventually released in January 2004, the band had reformed with a mostly new lineup, and work had begun on an Helmet album, Size Matters, which would be released later that year.

The compilation's track listing was selected by Hamilton.

Unsung: The Best of Helmet (1991–1997) received a positive reaction from critics. In their December 2004 review, Deseret News gave the album four out of five stars, reflecting, "In six years Helmet laid the foundation for the nu-metal movement that features Tool, Lamb of God, Slipknot and Korn. Helmet leader Paige Hamilton has since reorganized the band, but the classic Helmet will always be the standout. 'Repetition', 'Bad Mood', 'Iron Head' and the ever-popular 'Just Another Victim' (performed with Everlast's band House of Pain) give this compilation some power. 'Overrated', 'Sinatra' and the drawl of 'Milquetoast' will have Helmet fans reliving the glorious past."[7]

Michael Endelman of Entertainment Weekly gave it an A− in March 2004, writing, "Unsung is right. Without this underground metal-punk quartet, we wouldn’t have the subterranean guitar chunk and drum thunder of nu-metal superstars like Linkin Park. Imagine roaring rage delivered with laser-guided precision."[2]
