"Bad" is the seventh studio album by American singer Michael Jackson, released on August 31, 1987, by Epic Records. The album was produced over a three-year period from 1985 to 1987 and marked Jackson’s third and final collaboration with producer Quincy Jones. A dance-pop and R&B release, it reflected increased artistic control by Jackson, who composed and co-produced all but two of its tracks. Its themes include celebrity, romance, world peace, and self-improvement, and it features guest appearances by Siedah Garrett and Stevie Wonder. Following the commercial success of "Thriller" (1982), expectations for the album were high. Jackson adopted a more assertive musical style, incorporating digital synthesizer technology and elements of hard rock and funk. The album was accompanied by a new public image, including changes to his appearance, which generated mixed public reactions in the United States. The associated "Bad" tour, Jackson’s first solo world tour, grossed approximately $125 million and became the highest-grossing concert tour at the time.

"Bad" received critical acclaim, particularly for Jackson’s vocal performance and production, though some reviewers compared it unfavorably to "Thriller". It spent six consecutive weeks at number one on the Billboard Top Pop Albums chart and produced five number-one singles on the Billboard Hot 100: "I Just Can't Stop Loving You", "Bad", "The Way You
