The "Liturgical Night" of the 1975 Kirchentag with Peter Janssens inspired the founding members to seek their own paths in the field of contemporary Christian music.
The band is focused on music of the genre Neues Geistliches Lied, with content such as the responsibility for peace, justice and the environment.
[2] For the 1977 performance, the band was named after the Biblical Habakuk, whom Eckert described as a social prophet with a vision of life within a society.
[3] Eckert began writing song lyrics in 1979, such as "Halte deine Träume fest" (Hold on to your dreams).
[2] In 1993, the Habakuk song "Bewahre uns, Gott" (Keep us safe, God) was included in common Protestantn hymnal Evangelisches Gesangbuch as EG 171.
