When did the Beatles become solo artists?
Paul McCartney composed soundtrack music to The Family Way, with George Martin as arranger. A soundtrack album was issued in 1966, but McCartney did not play on it.
George Harrison released the first solo album by a Beatle, with the Wonderwall Music soundtrack in November 1968. Lennon followed a few weeks later, issuing his notorious Two Virgins album with Yoko Ono.
Lennon and Ono recorded "Give Peace A Chance" in 1969, crediting the song to the "Plastic Ono Band", and also "Cold Turkey" later that year, then "Instant Karma!" early in 1970.
Paul McCartney and Ringo Starr issued their first solo albums, McCartney and Sentimental Journey, in April 1970, but there were no singles from either. George Harrison followed in December with All Things Must Pass, and its single "My Sweet Lord".
Well I'm not sure if you can call them Artists but the band Oasis were influenced by The Beatles. The drummer in Oasis is Ringo Starr's son, Zak. Also, Yoko Ono ( John Lennon's 2nd wife) was an artist and helped design some of John Lennon's solo album covers.Also, the Jonas Brothers were influnced by the Beatles. The song BB Good sounds like the Beatles song.
A turnaround in the Beatles' approach to making music. Whereas Sgt. Pepper and Magical Mystery Tour were psychedelic, gaudily-styled group efforts, the "White Album" (formally titled The Beatles) was a pared-back, more simplified, more individual record by the Beatles. John Lennon compared the album to four solo artists working with a backing band, instead of the Beatles working as a team like they had in the past. The fact that there was no group photo…
After the Beatles broke up, Paul released a solo album ("McCartney") on which he played every instrument, recorded "Ram" with a few session musicians, then formed a little band called Wings. Remember them? Other than as a Executive Officer of Apple Music, I wouldn't categorize what McCartney did after he left the Beatles as a Job. He has created/produced his own albums as well as produced/mixed many other artists music. He continues to do so.
