SIOT-TAL, with organisational support from Casa della Musica, offered yesterday the second edition of TAL-Concert in Barcolana, the “deepest concert in the world” hosted on the majestic and unusual stage of Grotta Gigante. The numerous audience experienced an experience, in the “heart of the earth”, capable of uniting music, culture and territory, thanks to the evening’s protagonist Marco Castelli, internationally renowned saxophonist and composer, who guided the audience in an evocative sonic journey between jazz, theatre and acoustic experimentation, in perfect harmony with the natural environment of the karst cavity.
