"Hush" is a song by Tool from their 1992 debut EP Opiate, recorded by producer Sylvia Massy at Sound City Studios. It was the only single released from Opiate and was the first song that helped establish the band's reputation. The lyrics protest Tipper Gore and censorship, which is a recurring theme in Tool songs. The song was first recorded on a self-titled demo tape variously known as Toolshed and 72826, recorded in mid-1991. This demo version is not the same as the studio recording that appears on Opiate.
