Staind ( STAYND) is an American rock band formed in 1995. The original lineup consisted of lead vocalist and rhythm guitarist Aaron Lewis, lead guitarist Mike Mushok, bassist and backing vocalist Johnny April, and drummer Jon Wysocki. The lineup has been stable outside of Wysocki's departure in 2011, who was replaced by Sal Giancarelli. The band has recorded seven studio albums: Tormented (1996), Dysfunction (1999), Break the Cycle (2001), 14 Shades of Grey (2003), Chapter V (2005), The Illusion of Progress (2008), and Staind (2011).

In March 2010, Aaron Lewis stated the band would start working on their seventh studio album by the end of the year. Lewis had finished recording his country-tinged solo EP and had started a nonprofit organization to reopen his daughter's elementary school in Worthington, Massachusetts. Guitarist Mike Mushok stated in a question and answer session with fans that the band was looking to make a heavy record, but still "explore some of the things we did on the last record and take them somewhere new for us". In a webisode posted on the band's website, Lewis stated that eight songs were written and that "every one of them is as heavy or heavier than the heaviest song on the last record".  In December 2010, Staind posted three webisodes from the studio, which featured the band members discussing the writing and recording process of their new album. They announced that as of April 20, the band had completed the recording of their untitled seventh album and would release it later that year.  On May 20, 2011, Staind announced that original drummer Jon Wysocki had left the band. Drummer Will Hunt filled in for a few dates, while Wysocki's drum tech Sal Giancarelli filled in for the rest of the tour. Three days later, it was reported that Staind's new album was originally called Seven, but was renamed Staind. It was released on September 13, 2011. The first single "Not Again" was released to active radio stations on July 18. The song "The Bottom" appeared on the Transformers: Dark of the Moon soundtrack. On June 30, Staind released a song called "Eyes Wide Open" from their new record. "Eyes Wide Open" would later be released on November 29 as the album's second single. On July 12, Staind released the first single "Not Again" through YouTube and was officially released/available on July 26.  In November 2011, the band announced through their YouTube page that Sal Giancarelli was now an official member. The band continued to tour heavily into 2012; embarking on an April and May touring with Godsmack and Halestorm, and the Uproar Festival in August and Setpember with Shinedown and a number of other artists.
