Moki collaborated with her husband, the American jazz trumpeter, Don Cherry, throughout her lifetime – they performed in concerts as Organic Music, where her artworks were also displayed, and ran workshops for children.

In Stockholm, Karlsson met a Sierra Leonean student named Ahmadu Jah (1936–2018), who had received a scholarship to study engineering at KTH Royal Institute of Technology.

[6] Moki graduated from Beckman's in 1966 and traveled to New York to work in fashion and join Don who was living there at the time.

Moki was receiving recognition as a young artist-designer too and was offered a permanent design job with the photographer Bert Stern, but instead returned to Stockholm with Don and Neneh.

In 1969, Moki and Don left Stockholm with their children to go to New York where they rented a loft in Manhattan and then a house in Congers.

Moki created costumes and artworks in the dome during this residency, which included a mandala that she painted on the floor each day.

Moki made the sets and costumes for the group, who performed in Malmö, Gothenburg, and in Stockholm at Moderna Museet.

During the nineteen eighties, Moki had exhibitions of her artwork across Sweden and New York and she and Don collaborated less (although she still designed some album sleeves and clothing for him).

There has been increasing interest in her art since her death in 2009 and she has had solo exhibitions internationally at Moderna Museet, Stockholm in 2016, Air De Paris, Paris in 2018, and Kerry Schuss, New York City in 2019, as well as being included in group exhibitions most recently at Loyal Gallery in 2019, Malmö Konstmuseum in 2017 and at "The House of Fame",[7] Linder Sterling's expanded retrospective at Nottingham Contemporary in 2018.
