Kūlgrinda is a prominent Lithuanian folk music ensemble that has been dedicated to preserving, promoting, and performing traditional Lithuanian folk music since their formation in 1990. The group has become synonymous with the sounds of ancient Baltic culture, often incorporating sacred chants, ritualistic songs, and historical instruments in their performances. Kūlgrinda takes inspiration from Lithuania's pagan past, often celebrating nature, gods, goddesses, and traditional seasonal festivities through their music. The band’s name itself is derived from the term "kūlgrinda," which refers to a secret, underwater causeway built by the ancient Balts, hinting at the group's connection to hidden realms of history and spirituality.

Over the years, Kūlgrinda has enriched the Lithuanian music scene with an array of thematic releases that explore different facets of Baltic mythology and cultural heritage. Through albums such as "Giesmės Didžiajai Deivei" (Hymns for the Great Goddess), "Giesmės Austėjai" (Hymns for Austėja), "Laimos Giesmės" (Hymns for Laima), "Sotvaras," and "Ugnies Apeigos" (Fire Rituals), the ensemble has offered listeners a profound auditory journey into the spiritual traditions of Lithuania. Kūlgrinda's work stands as both a musical experience and a form of cultural education, gaining both local admiration and international interest in the rich tapestry of Baltic folklore.
