The choir LANGAS was founded in 1990 by the conductor Rita Kraucevičiūtė. Until 1995 the choir belonged to various artistic organizations, such as the Contemporary Art Centre, the art gallery "Langas" and the Lithuanian Painters' Union.

In 1995, the choir LANGAS was invited to rehearse into a newly consecrated church of St. Francis and St. Bernardine (Bernardine). Thus, there appeared an opportunity to form a school of singing and to train children from the age of five. At present, LANGAS is also a part of St.Bernardine school of singing. At this school, much attention is paid to the development of vocal singing. Every singer has a possibility to train his or her vocal skills individually and to take part in closed vocal concerts.
