McCartney is the debut solo studio album by the English rock musician Paul McCartney, released on 17 April 1970 by Apple Records. McCartney recorded it in secrecy, mostly using basic home-recording equipment at his house in St John's Wood. Mixing and some recording took place at professional London studios. In its loosely arranged performances, McCartney eschewed the polish of the Beatles' records in favour of a lo-fi style. Apart from occasional vocal contributions by his wife, Linda, McCartney performed the entire album alone by overdubbing on four-track tape.
