On Thursday, October 22, the Beatles Museum Club in Brescia hosts the presentation of the book "The Rock Triangle" by Riccardo Russino, in dialogue with Emi Baronchelli. The volume retraces the history of George Harrison, Eric Clapton, and Pattie Boyd, among romantic ties, friendships, and songs that have become legendary. A narrative that intertwines the personal stories of the protagonists with the history of rock music. Accompanying the evening are live performances by the Due Quarti Acoustic Duo, who will interpret some of the most representative pieces by Harrison and Clapton.
