Sundstrand was asked to join Play by the group's manager, Laila Bagge, who discovered Sundstrand at her dancing school after seeing her performing at the school. Bagge asked her to be the first member of Play.
In Play, Sundstrand sang alto harmonies and solos. After the band's first split, Sundstrand moved to NYC after being signed to New York-based modeling agency Model Management Group (MMG).
In 2009, Play announced their reunion with original members Anaïs Lameche and Fanny 'Faye' Hamlin. However Sundstrand was not asked to join the reunion. She stated in an official statement that she received a call from Hamlin who told her about the reunion but said they didn't want her back.
Since Play ended in 2005 Sundstrand was signed to Model Management Group (MMG) based in New York (the same agency her bandmate Rosanna Munter was signed). Sundstrand did some modeling for a while and even did some benefit fashion shows. However, in 2005 and 2006 Sundstrand performed around New York City with friend singer Chris Trousdale (who she previously worked with in Play).
Between 2005 and 2006, Sundstrand was back in the studio where she went to work recording her debut solo album. She recorded two solo songs, "Say It Again" and "Press Rewind" which she debuted during concerts with Trousdale. In 2006 the duo recorded a duet titled "If Only" which they recorded in Sweden. The music video for the song was released via their choreographer Claudia Swan's YouTube account a few years after they filmed it.
In 2008, Sundstrand moved from New York to Los Angeles, California where she starred in two indie films. Gone Astray, which was filmed in 2008.
