The average band is lucky to make it through 50 months of existence. But the Tannahill Weavers is not the average band.

The group has persevered more than 10 times longer than that, and Saturday night they take the Caltech stage in the midst of a tour celebrating their golden anniversary in a Pasadena Folk Music Society show. The tour is also in support of their newest studio album, “Orach.”

The band performs music of its native Scotland. The Tannahill Weavers boast a diverse repertoire spanning centuries of Scottish music, with fiery instrumentals, topical songs, ballads and lullabies. The Celtic stars feature dynamic rhythmic accompaniment, rich vocals and unforgettable shows.

Founded in Paisley, Scotland, the group takes its name from the town’s historic weaving industry and local poet laureate Robert Tannahill.
