PORT Fairy's popular classical music event celebrates its 20th birthday this weekend with another exemplary line-up of musicians. Among them is classical guitarist Karin Schaupp, who will perform the David Williamson musical-play Lotte's Gift, which was written specifically for Schaupp and tells the story of Karin, her mother Isolde and grandmother Lotte. Among the international performers is pianist Grace Kim and cellist Teije Hylkema from Amsterdam. The T'ang Quartet also returns to the seaside town to perform works by Haydn and Brahms. There will also be a special Schumann concert, a performance by Tinalley String Quartet and a triumphant return from Port Fairy's own international star Anna-Lee Robertson.
