Third studio album: Something's Changing (2016–2018)
In the spring of 2016, Rose was inspired by the number of tweets and Spotify streams coming from Latin America and decided to give something back to her fans in those territories. Rose offered a deal to her fans: "If you book me a gig, I'll come and stay."
For two months in 2016, Rose took her guitar and backpacked around Ecuador, Peru, Chile, Argentina, Paraguay, Uruguay, Brazil, and Mexico, playing free shows and staying with fans. While on this tour, she made a documentary, 'Something's Changing', of her experiences. The documentary was later screened at her concerts in beginning in 2017 and is available to stream on her official YouTube channel.
Due to the lukewarm critical reception of her sophomore album and the prospect of the lack of creative control for her forthcoming third album, she left Columbia Records in 2016 and later signed with the independent label, Communion Records, to release her third album.
Upon returning to the UK from her travels in Latin America, Rose began work on her third album, Something's Changing. The album was recorded in 17 days with producer Tim Bidwell, bassist Ben Daniel and drummer Chris Boot in Brighton. The album features appearances from Daughter's Elena Tonra and Matthew and The Atlas' Emma Gatrill. On two tracks vocal harmonies are provided by The Staves ("Floral Dresses" and "Is This Called Home").
In December 2016, Lucy went out on an intimate lamplit tour of UK Libraries as part of the Get It Loud In Libraries initiative www.getitloudinlibraries.com
Following the release of Something's Changing, Rose released two singles as bonus tracks: "End Up Here" in October 2017 and "All That Fear" in January 2018, both with accompanying music videos.
In May 2018, Rose announced she was going to release a Something's Changing remix album, which would feature new versions of every track on Something's Changing except "Floral Dresses", "Find Myself" and "I Can't Change It All", plus an "All That Fear" remix. Among the producers who remixed her tracks are musicians/producers Fryars, Get Cape. Wear Cape. Fly and Liz Lawrence. The digital-only album was released 6 July 2018.
Rose featured on the track "Thank You" from Logic's fourth studio album, YSIV, released on 28 September 2018. She previously featured on his track "Innermission" from Logic's second album, The Incredible True Story, and on "Anziety" from his third album, Everybody.
