Tommy is the fourth studio album by the English rock band The Who, a double album first released in 23 May 1969. The album was mostly composed by guitarist Pete Townshend, and is a rock opera that tells the story of Tommy Walker, a "deaf, dumb and blind" boy, including his experiences with life and his relationship with his family.
 
Townshend came up with the concept of Tommy after being introduced to the work of Meher Baba, and attempted to translate Baba's teachings into music. Recording on the album began in September 1968, but took six months to complete as material needed to be arranged and re-recorded in the studio. Tommy was acclaimed upon its release by critics, who hailed it as the Who's breakthrough. Its critical standing diminished slightly in later years; nonetheless, several writers view it as an important and influential album in the history of rock music. The Who promoted the album's release with an extensive tour, including a live version of Tommy, which lasted throughout 1969 and 1970. Key gigs from the tour included appearances at Woodstock, the 1969 Isle of Wight Festival, the University of Leeds, the Metropolitan Opera House, and the 1970 Isle of Wight Festival. The live performances of Tommy drew critical praise and revitalized the band's career.
 
Subsequently, the rock opera developed into other media, including a Seattle Opera production in 1971, an orchestral version by Lou Reizner in 1972, a film in 1975, and a Broadway musical in 1992. The original album has sold 20 million copies and has been inducted into the Grammy Hall of Fame. It has been reissued several times on CD, including a remix by Jon Astley in 1996, a deluxe Super Audio CD in 2003, and a super deluxe box set in 2013, including previously unreleased demos and live material.
 
The album was commercially successful, reaching No. 2 in the UK album charts. It peaked at No. 7 in the US in 1969, but in 1970 it re-entered the charts, at which time it went on to peak at No. 4. It sold 200,000 copies in the first two weeks in the US alone, and was awarded a gold record for sales of 500,000 on 18 August. "Pinball Wizard", "I'm Free" and "See Me, Feel Me" were released as singles and received airplay on the radio. "Pinball Wizard" reached the top 20 in the US and the top five in the UK. "See Me, Feel Me" reached the top 20 in the US and "I'm Free" reached the top 40. An EP of selections from the album was planned to be released in the UK in November 1970, but was withdrawn. As of 2012, Tommy has sold 20 million copies worldwide.
