Persevera built their 2023 debut "Genesis" unconventionally, releasing each of the album's thirteen tracks as a standalone single across two and a half years before compiling them into a 63-minute full-length.

Pietro Bernal is a São Paulo-based guitarist and composer working in the tradition of high-precision instrumental heavy metal and shred, releasing his debut album "Infinite Way" in 2022.
