Trillium

Trillium is the primary creative vehicle for American singer-songwriter and vocal coach Amanda Somerville, established in 2011. While Somerville is a prolific collaborator within the European metal scene (notably with Avantasia, Epica, and Kamelot), Trillium represents her most personal and stylistically diverse work.

The project's debut, 'Alloy', was developed in collaboration with producers like Sascha Paeth, resulting in a sound that bridges the gap between traditional symphonic metal and modern hard rock. Unlike many of its peers in the Dutch and German scenes, Trillium incorporates significant industrial and electronic elements, moving away from the 'fairytale' aesthetic toward a more grounded, psychological intensity. Critically, the project is praised for Somerville's technical vocal prowess and the sophisticated songwriting that avoids the genre's tendency toward over-indulgence. It occupies a unique space in the metal taxonomy, appealing to fans of both the theatricality of Nightwish and the riff-driven power of Halestorm.
