The Hell We Create

“Expedition: Light/Dark” is the musical journey crafted by Sierra — DeathTheorem. This album stands as a testament to her extraordinary range as a musician, blending soaring angelic vocals with crushing gothic metal riffs, sweeping violins, and thunderous cinematic drums.

Every track carries her signature talent: emotional depth, fearless experimentation, and a sound that feels both ethereal and apocalyptic. Expedition: Light/Dark explores the struggle between heaven and hell, strength and vulnerability, creation and destruction — a theme Sierra brought to life with unmatched passion.

This release is shared to honor her work, her imagination, and the legacy she leaves behind for everyone who loved her and everyone who will discover her for the first time. May her music continue to echo, inspire, and light the path for others.

Thank you for listening to her story.
Thank you for keeping her music alive.
— In loving memory of Sierra, “DeathTheorem”
