There are several bands called ‘baalberith’, named after a demongod, an entity also known as Ba’al Berith and closely related to El Berith (sort of spiritual ‘twins’). I am not going to write down an essay on this grand duke; I guess the internet, and the Old Testament, might satisfy your quest for knowledge.
On the September 21st 2014-update, you can read the review I wrote for the Satanath split-album The Antichristian Symphonies, a five-way split with e.g. English act Baalberith. And now we can enjoy their fourth full length in eight years of existence.
I would like to refer to the review on the split for this band’s history, and to the worldwide net for their huge discography.
