Tearing up the rulebook at this year’s Proms are the Budapest Festival Orchestra and conductor Iván Fischer, who – for one day only – hand over the reins to the Proms audience. We can’t tell you what you’ll hear at this concert, because we don’t know yet.

Be there on the night to have your say over which of more than 200 classical pieces the ensemble will play at a moment’s notice. It’s a spectacle unlike any other – all woven together by members of the orchestra bringing a bit of extra Hungarian flair to proceedings.
