Olvido is an album about grief and confrontation. It explores the many different and often contrasting emotions that come after loss.

Nostalghia is a music project from Mexico City, created by sole member Alex Becerra, who is also in charge of the recording and production of the albums. In less than three years, he has released eight full-length albums:
Obsequies for Lost Memories (August 2020) Lifeless (February 2021) Here, at the end of all things (November 2021) Olvido (March 2022) Au milieu de l'hiver (July 2022) Wounds (October 2022) The Last Path (May 2023) Duelo (July 2023)

Throughout his discography, Nostalghia has explored different approaches to music, including a variety of genres and instrumentation: from atmospheric black metal to post-punk, shoegaze, dark folk, progressive rock and even jazz. Nostalghia often collaborates with multi-instrumentalist Valeria Dávila, who provided vocals and a clarinet solo for Olvido's first track: Abandon.
