You could blame (or praise) the Beatles for merging orchestral sounds with rock and roll in 1966, but the concept was taken a step further a couple years later by Deep Purple. <br />In 1969, Purple released the album, ‘Concerto for Group and Orchestra,’ which featured the hard rockers and the Royal Philharmonic Orchestra performing Jon Lord‘s three-movement composition. <br />Thus, the idea of rock and roll bombast being married to classical bombast was born. In 2011, Deep Purple revisited that idea with a concert at the Arena di Verona, a Roman amphitheater originally built in 30 A.D. That concert has now made its way to DVD as ‘Live in Verona.’
