Malcolm James McCormick (January 19, 1992 – September 7, 2018), known professionally as Mac Miller, was an American rapper, singer, songwriter, and record producer. Born in Pittsburgh, Pennsylvania, Miller began his career in the city's hip hop scene in 2007, at the age of fifteen. In 2010, he signed a record deal with Pittsburgh-based independent label Rostrum Records, with whom he had his breakthrough with the mixtapes K.I.D.S. (2010) and Best Day Ever (2011).
Miller's debut studio album, Blue Slide Park (2011), became the first independently distributed album to top the US Billboard 200 since 1995. In 2013, he founded the record label imprint REMember Music. After his second studio album, Watching Movies with the Sound Off (2013), he left Rostrum and signed with the major label Warner Bros. Records in 2014. With them, he released three studio albums: GO:OD AM (2015), The Divine Feminine (2016), and Swimming (2018). For Swimming, he was posthumously nominated for a Grammy Award for Best Rap Album. He also served as a record producer for various artists, including himself, under the pseudonym Larry Fisherman.
Miller struggled with substance abuse, which was often referenced in his lyrics.
