You can't get much better than the Philharmonia Orchestra, and you're in for a treat tonight as they perform Mahler's Symphony No.5. Conducted by Andris Nelsons, Håkan Hardenberger is also taking on Gruber's Aerial, an amazing concerto roller-coaster in two main parts. Virtuoso's at work. Over 7s only. Latecomers may not be admitted.
