successful and influential artists of her generation, and a return to the inspiring and personal music that Amos is known for all around the world." The 2-CD set The Light Princess (Original Cast Recording) was released on October 9, 2015, via Universal/Mercury Classics. Apart from the original cast performances, the recording also includes two songs from the musical ("Highness in the Sky" and "Darkest Hour') performed by Amos. 2016–present: Native Invader, Christmastide and Ocean to Ocean On November 18, 2016, Amos released a deluxe version of the album Boys for Pele to commemorate the 20th anniversary of the original release. This follows the deluxe re-releases of her first two albums in 2015. On September 8, 2017, Amos released Native Invader, accompanied by a world tour. During the summer of 2017, Amos launched three songs from the album: "Cloud Riders", "Up the Creek", and "Reindeer King", the latter featuring string arrangements by John Philip Shenale.

The initial inspiration for the album came from a trip that Amos took to the Great Smoky Mountains (Tennessee-North Carolina), home of her alleged Native American ancestors; however, two events deeply influenced the final record: in November 2016, Donald Trump was elected President of the United States of America; two months later, in January 2017, Amos' mother, Mary Ellen, had a stroke that left her unable to speak. Shocked by both events, Amos spent the first half of 2017 writing and recording the songs that would eventually form Native Invader. The album, released on September 8, 2017, was presented in two formats: standard and deluxe. The standard version includes 13 songs, while the deluxe edition adds two extra songs to the tracklist: "Upside Down 2" and "Russia". Native Invader was well received by most music critics upon release. The album obtained a score of 76 out of 100 on the review aggregator website Metacritic, based on 17 reviews, indicating "generally favorable reviews".
