From Ray Chen’s YouTube channel comes this video of the run-up to his performance of Lalo’s Symphonie espagnole in San Francisco last October.

‘Ever wonder what the soloist is doing before he/she walks out onto the stage?,’ he writes. ‘Practicing? Eating? Or perhaps doing some sort of secret warm up technique that ensures a successful concert? Well now you get to see what happens! Join me backstage at one of the most prestigious venues - Davies Symphony Hall with the San Francisco Symphony and conductor Cristian Macelaru!’
