In a Facebook post, Lee revealed that the new album is titled "Synthesis". According to Lee, the album is an orchestral piece that contains instruments such as brass and other orchestral elements. She also revealed that David Campbell, who worked on all of the band's previous albums, would return to compose for the new project. Lee said that the album is about "orchestra and electronica", and that the band is taking selected songs from their previous albums and stripping out the rock guitars and drums, rebuilding them into a classical arrangement reminiscent of a soundtrack. The album contained two new original songs, one titled "Hi-Lo" starring Lindsey Stirling. The first recording session for "Synthesis" took place on May 23, 2017, and a remake of "Bring Me To Life" was released as a single on August 18. On August 15, the band announced that recording "Synthesis" was in its final stages. Evanescence toured with a full orchestra in late 2017 in support of the album, and tickets were sold starting on August 18. The band later toured across the US, Australia and Europe. Each ticket purchased came with a digital copy of "Synthesis" after its release. On September 14, 2017, the single "Imperfection" was officially released.
