Duo Beltenstrum, composed of Sara Henry, mezzo-soprano, and Hideki Yamaya, Romantic guitar, specializes in the performance of late 18th-century and early 19th-century song repertoire.  Their aim is to revive long-forgotten gems by obscure composers as well as present well-known favorites by the likes of Mozart, Bellini, and Schubert, mostly arranged by guitarists of the period.
