Concert, violin Concerto

I Wanted to go to “The London Philharmonic Orchestra playing Beethoven Violin Concerto” it’s on Saturday, 4th of March at the National Concert Hall,I even booked a hostel thinking that 2 months would be ample time to get a ticket, how wrong I was, it sold out around the 10th of january. Just my luck. There is nothing else I would like to see until April so maybe I should book my ticket now.
