Along with italian bands like PFM, Le Orme and Banco, il Balleto di Bronzo is considered like one of the great groups of the progressive rock movement of the 70's. Lead by Gianni Leone (Keyboards and Voice) this band releases what is considered their best album "YS", one of the classics of all time progressive rock. It is a keyboard-oriented style, complicated instrumental passages and environments generally used in horror movies, we find in this work of art some influences of classical music and jazz, in combination with the energy of rock. Prepare yourself to enjoy a great deal of "YS", along with selections of the rest of their discography. Surely the performance of il Balleto di Bronzo during Baja Prog will be one of the moments with the most quality and nostalgia within the festival.
