In response to a commission from Count Troyer, who wanted a work closely modelled on Beethoven’s famous Septet op.20, Schubert – despite his fervent admiration for the older composer – resolutely struck out on his own by delivering an . . . Octet. While the enlarged forces opened his path towards symphonic writing, examination of the form and expression reveals a much more accomplished and personal composition than has generally been recognised by commentators. Isabelle Faust and her partners, enthralled by what is an exceptional work in every respect, offer us a new interpretation of it on period instruments.
