According to his friend Albert Stadler, Schubert's celebrated 'Trout' Quintet was based, at the request of the patron who commissioned it, on an earlier piece by Hummel for this unusual combination of instruments. Given the respective dates of Schubert's work and of Hummel's op.87, the latter was probably not Schubert's model; but its reputation as one of Hummel's finest compositions is amply justified here in this highly appropriate coupling.
