Last Dying is a solo instrumental metal music project, also known as One Man Band, created by musician and producer Guillermo D. Bouix in 2018. Since then, he has built a career spanning over four years, during which he has released two full-length albums titled "Pandemic" (released on January 30, 2020) and "Emptiness" (released on July 12, 2023), as well as two EPs: "Breadth" and "Wasteland," a collection of singles called "Singles 21 Collection," and a total of ten singles to date.

Last Dying's music is a unique combination of various subgenres of metal, ranging from death metal to melodic death metal, black metal, and most notably, alternative metal. Each musical project undertaken by Bouix is an opportunity to experiment and explore new sonic possibilities.
