It lies at the intersection of classical and jazz in the third appointment with the fifth edition of Il Centro della Musica, an event promoted by the Donizetti Theater Foundation in collaboration with the Bergamo City Council's Social Policies Department. Saturday, June 6 (5 p.m.) is in fact scheduled in the "Gavazzeni" Ridotto of the Donizetti Theater a concert entitled Le mezze stagioni, in which excerpts from Antonio Vivaldi's famous Four Seasons will be juxtaposed with jazz standards, in a unique, fascinating mix of sounds and colors. It will feature theOFI Jazz Acoustic String, one of the many emanations of the Italian Philharmonic Orchestra, a longtime partner of the Fondazione Teatro Donizetti. Creator of the project is violinist Cesare Carretta, as well as arranger and solo violinist, joined on the occasion by Silvia Maffeis (violin), Matteo Del Soldà (viola), Nicolò Nigrelli (cello), Nicola Ziliani (double bass) and Federico Negri (drums). The narrative thread of the concert follows the cycle of the seasons, understood not only as a natural phenomenon but as a metaphor for loves and the human condition. A journey that reflects the parable of life: every end already contains a new beginning. In Spring , Afro rhythms accompany the birdsong evoked by Vivaldi, while the melancholy of I'll Remember April intertwines with the lightness and swinging joy of Smile, It's Spring. InSummer the sudden fury of Vivaldi's storm is joined by the tale of an African American singing about his plight in Caesar's Blues, finally finding refuge in Summertime. In Autumn , the harvest festival described by Vivaldi meets the colors and rhythms of a cosmopolitan city in Autumn in New York, to the sweet melancholy of a fading love in Autumn Leaves. Finally,Winter opens with the Adagio from Vivaldi'sWinter , then runs through a selection of Christmas carols reinterpreted in an engaging swing rhythm, between intimacy and celebration.
