Elfrida Andrée, Swedish organist and composer, was born in Visby, Feb. 19, 1841, and died in Göteborg, Jan. 11, 1929. She studied composition with Ludwig Norman at the Royal Academy of Music, Stockholm, and later took lessons with Niels Gade in Copenhagen. At the same time, she studied telegraphy and was the first woman telegraph operator in Sweden. She was a keen supporter of the suffragette movement and a pioneer among Swedish women as an organist and composer. "Two Pieces" includes two small music pieces from Elfridas "Fem smärre tonbilder" ("Five small music images"), original composed for piano but now arranged for Trombone quartet.
