1994–present: Evanescence In 1994, Lee played Moody a cassette tape of her playing guitar and singing a song she wrote and the two began working on music at Lee's home. They were soon performing acoustic sets at bookstores and coffee houses in Little Rock and co-founded Evanescence. Lee wanted to combine her various musical tastes, "bringing something from the cinematic and classical symphonic world and marrying it to metal, hard rock and alternative music." Evanescence was signed by
Wind Up Records in 2001, and moved to Los Angeles, where they completed their debut album,
Fallen (2003). including three songs originally from their earlier independent records. In October 2003, Moody left the band in the middle of the
Fallen tour, citing "creative differences". In Lee's termination letter to their manager, she stated that Moody was physically and verbally abusive to her. and his influences were "a lot different" than hers. Lee called former
Cold guitarist Terry Balsamo to replace Moody on the
Fallen tour, and he soon became Evanescence's permanent lead guitarist and Lee's co-writing partner. She and Balsamo "clicked" and "connected on a lot of musical interests". When asked if the track was about Moody, Lee said, "If I answer that, then I'm not hiding anything anymore. But I just sort of answered it, didn't I?". Other songs Lee wrote throughout these months included "
Lacrymosa" and "Together Again". Lee collaborated with Balsamo, co-writing music together for Evanescence's second album,
The Open Door (2006). The writing experience for
The Open Door was "the best process" Lee ever had because she had "free reign"[sic] and could "do whatever I wanted without being judged". In 2006, Lee said that when she listened back to
Fallen, she "hear[d] all the vulnerability and the fear and all the childish things in me that are just human." While Lee was drowning in the misery of her experiences in
Fallen, she said
The Open Door is largely about her acknowledging her issues and deliberating "what do I have to do to work this out." After the end of
The Open Doors tour, Lee took a break to recollect herself and live life away from the industry. and took
harp lessons out of a desire to learn the instrument. In 2009, Evanescence began playing live shows again, with Lee realizing that she missed this part of her life, stating: "I had to get back together with all the guys, and we practiced all the old stuff ... and I enjoyed it so much. I started falling back in love with that part of me, the Evanescence part. I'd kind of been doing everything else, writing-wise, by myself, and I was like, 'Oh yeah, I love this stuff too. Maybe we should all make a record!'" Its lyrical themes include Lee "falling back in love" with Evanescence, her being inspired by nature and the ocean, brokenness, the quest for freedom, and falling in love. Different from
The Open Door, which was "all about me and my personal experiences",
Evanescence also includes Lee's musings on events that occurred to others in her life. "But really, whatever makes me feel the most, that's what's on the record, because that's what I need to get off my chest." In January 2014, it was reported that Lee had filed a lawsuit against Wind-up Records for $1.5 million in unpaid royalties owed to the band. The album's release was followed by the
Synthesis Live concert tour in which the band performed with a live orchestra for the first time. In April 2020, Lee announced the release date of Evanescence's fifth album,
The Bitter Truth. In a
Q&A with
Forbes in May 2020, Lee mentioned that the "image and idea" of the band from the early days was "something that combined multiple dramas, from the dramatic to the rock to the classical to the score", and that although many things have changed since, the "idea that started this whole thing is still there". Four songs from the album were released as singles throughout 2020 and 2021 during the
COVID-19 pandemic, while a virtual live-streamed show was performed by the band from their recording base at Rock Falcon Studio,
Nashville, in December 2020. The album was released on March 26, 2021.

Believe, and sang backup vocals on two songs with
supergroup The Damning Well, though her vocals were taken off the final release due to record label issues. For
Walt Disney Records' September 2008 release of

Nightmare Before Christmas soundtrack. She stated that collaborating on the song helped her cope with the passing of her brother, Robby. In 2019, Amy collaborated with
Lindsey Stirling on Stirling's 2019 album

Osaka on February 16, 2020, where Lee performed as a guest, but it was finished through file sharing due to the coronavirus pandemic. On October 30, 2020, Lee featured on the
Bring Me the Horizon song "One Day The Only Butterflies Left Will Be In Your Chest As You March Towards Your Death" from their EP
