Two distinct visions of the natural world provide the bookends for tonight鈥檚 concert: Tapiola, Sibelius鈥檚 homage to the fabled Finnish god of the forest; and Four Sea Interludes, Britten鈥檚 glorious evocation of his beloved Suffolk coastline. In between, two pieces that demand the best from string soloists: cellist Jakob Kullberg will be in the spotlight for a beautiful work by Kaija Saariaho, one of Finland鈥檚 leading living composers, before conductor John Storg氓rds performs and directs Kurt Weill鈥檚 vibrant Violin Concerto.
