In May 2018, they released their first EP “Decisions”, followed by the single “Another Ending” later that year, which were both well received by the European Visual Kei community.
With a heavier musical direction and a strong involvement of guitarist Momo's vivid, detailed artwork, GAZTREA crafted their second EP 'Incantation'', which also marked the band becoming a quartet with bassist Cozmo joining. Exploring a darker concept based around witchcraft and ominous rituals, the EP released in June 2019 in two versions, landing them the title ''Newcomer of the Month'' in Orkus! Magazine.
After playing live shows all around Germany with bands like Esprit D'Air and VII ARC and supporting Mister Misery on their “The Unalive Tour”, GAZTREA went back into their home studios in 2020 and embarked on the journey of writing their first full length album. Starting with their new song ''Sunrise'', a number of singles foreshadows the upcoming album ''CELESTIA'' that will not only explore new territories both soundwise and visually.
