All three albums included in the box set are noted for their carefree and sometimes experimental nature, due to the circumstances under which they were recorded. The majority of the material on each album was recorded in McCartney's home studio, with him performing all instrumentation and vocals aside from the above exceptions.
McCartney consists mainly of acoustic tracks, some of which are instrumentals, and contains "
Maybe I'm Amazed", one of McCartney's most popular solo songs despite the studio version never receiving release as a single. The album was subject to harsh criticism at the time of its release but attained a much more positive reputation in later decades, being noted as an early example of
lo-fi music. The experimental
McCartney II consisted of recordings made in June 1979, once again at McCartney's home in Scotland. The album spawned the successful single "
Coming Up", which reached number two in the UK. A live version of the track, recorded in 1979 with
Wings, was included as a B-side and was more successful than the studio recording in the US, reaching the top of the chart. Two further singles were released, the minimalist "
Waterfalls" and the experimental "
Temporary Secretary", with the latter being released exclusively as a 12" single. "Waterfalls" became a top 10 hit in McCartney's home country, reaching number 9, The third album in the set,
McCartney III, was released in December 2020, forty years after its predecessor. Aside from "When Winter Comes", an acoustic track dating back to 1992, the album was recorded at McCartney's home studio in Sussex during the
COVID-19 pandemic. The album's sound is similar to the material McCartney recorded with his band. "
Find My Way" was released as the album's lead single the same day as the album's release. Unlike his previous two self-titled albums,
McCartney III received positive reviews upon its release. A "reimagined" version of the album, entitled
McCartney III Imagined, was released the following year and features covers and remixes of the album's tracks featuring
Beck,
EOB,
Dominic Fike and more. ==Reception==
