The band Hangar was formed in November 1997 with the initial aim of playing covers of some of the bands all the members liked. At the time, Hangar was composed by Michael Polchowicz (vocals), Cristiano Wortmann (guitar), Felipe Trein ( bass) and Aquiles Priester (drums).

After the recording of their first album, Last Time (released in 1999), Nando Mello replaced Felipe Trein as bass player. At the end of that year, the band suffered a new alteration with the departure of guitar player Cristiano Wortmann, due to musical differences. In his place, after various tests with guitar players of Porto Alegre, in came Eduardo Martinez, from the extinct band Panic, which during the 90´s was of great importance to the national heavy metal scene.
