Ghostlights is the seventh full-length album by Tobias Sammet's German metal opera project Avantasia.

[7] The story follows the protagonist as he continues his journey with a group of scientists willing to find a way to align everybody's personality so they can understand each other and make the world a better place.

[7][11] Describing the second and longest track "Let the Storm Descend Upon You", one of the last to be written for the album, Sammet commented:[8] [...] it's a big sounding arrangement with a lot of things that do not make sense according to the book of rules on how to compose a song.

[8] Sammet compares the track "Draconian Love" to The Metal Opera's "Avantasia" and The Wicked Symphony's "Dying for an Angel".

Herbie Langhans, who guest performs as co-lead singer, sung his parts an octave lower than Sammet at Sascha Paeth's suggestion, so that their voices sound more different from each other.

[12] A review by the AntiHero Magazine found that the album was one of Avantasia's "strongest releases to date" and that it featured the darkest atmosphere Sammet had created so far.

The Sonic Seducer's reviewer wrote that the album had "no musical limits" and that all guest singers harmonized well with Sammet's vocals.
