2) Bellatrix were an Icelandic rock group. The group was founded in 1992 in Keflavík as 'Kolrassa krókríðandi' ("Blackassed motherfuckers") by four women, all aged sixteen: Eliza Geirsdóttir (vocals and violin), Sigrún Eiríksdóttir (guitar), Ester Bíbí Ásgeirsdóttir (bass guitar) and Birgitta Vilbersdóttir (drums).
The band released the mini-album "Drápa" ("Slaughter") in 1992.
In 1994, they released "Kynjasögur" ("Family Stories") with Anna Margrét Hraundal (guitar) and Karl Ágúst Guðmundsson (trumpet and keyboard) replacing Birgitta.
Two years later, in 1996, they released "Köld eru kvennaráð" ("Cold are the Petticoat Government"). This album developed their style more, refining the punk and building a poppier side as well.
They also released "Stranger Tales" in 1995, which featured some English versions of Icelandic songs. This was also their first CD published under the name Bellatrix.
In 1999 they signed to Fierce Panda and released "It's All True" in 2000, also under the name Bellatrix.
They co-headlined a British tour with Coldplay and split the following year. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
