The name derives from "Beerenmoos" (berry bog), a part of the Haspelmoor in the district of Fürstenfeldbruck that was planned to be transformed in a large airport and a waste dump, and "Blosn", a Bavarian word for "group".

Three years later, their first hit Gott mit dir, du Land der BayWa, was broadcast on the Bayerischer Rundfunk (BR) television channel.

[4] The group announced in August 2011, they will play a final concert in January 2012 and then disband.

[7] The band has used their music to protest against multiple projects; amongst them were the planned nuclear reprocessing plant Wackersdorf plant in Wackersdorf,[4] the Bundesautobahn 94,[8] as well as several scandals of the long time governing party of Bavaria, the Christian Social Union of Bavaria.

[9] In 2001, the Bavarian ministry of education disallowed the song Gott mit dir, du Land der BayWa, which was the band's first hit, from being used in a song book for the eighth grade for "lampooning the Bavarian national anthem"[10] and ordered the whole order of books, 75,000 copies, to be destroyed.
