Fair Warning is the fourth studio album by American rock band Van Halen. Released on April 29, 1981, by Warner Bros. Records, the album peaked at number 5 on the Billboard 200, while the single "So This Is Love?" failed to reach Billboard Hot 100, peaking at number 110. The album sold more than two million copies in the United States, but was still the band's slowest-selling album of the David Lee Roth era. Despite the album's commercially disappointing sales, Fair Warning was met with mostly positive reviews from critics. The Village Voice's Robert Christgau rated Fair Warning a B−, while The Rolling Stone Album Guide, gave the album two-and-a-half stars out of five.
