We've attended this evening the concert by Joshua Bell playing with the National Orchestra of Spain (ONE) conducted by Dima Slobodeniouk. The program included a "Meditation" by Tchaikovsky and Glazunov's violin concerto. Bell isn't one of my favourite violinists but I was very interested in listening live to his Stradivarius which has a funny story behind: http://www.joshuabell.com/story-his-violinThat instrument sounds truly amazing, we got 6th row seats to be able to hear it cleanly. The tone of the treble notes is so smooth and clear, yet loud and forceful. It's been a delight attending this concert.
