Pet Sounds is the 11th studio album by the American rock band the Beach Boys. Released on May 16, 1966, it met a lukewarm critical and commercial reception in the United States, but received immediate success abroad, where British publications declared it "the most progressive pop album ever". It charted at number two in the UK but number ten in the US, a significantly lower placement than the band's preceding albums. In later years, Pet Sounds garnered enormous worldwide acclaim by critics and musicians alike, and is regarded as one of the most influential albums in the history of popular music.
