Flood Tide is a live, outdoor, musical performance on the afternoon of Sunday 4 July 2010, generated by the flow of the River Thames.
First performed in 2008, this production of Flood Tide is the most ambitious yet, with a record number of musicians performing for the duration of a tide cycle.
They'll be performing continuously between 2pm at 8pm today, on the Festival Riverside, near Festival Pier. Starting very quietly at first, the music will build to 5pm, and then wane again, in time with the tide.
Watch the video of the 2009 performance, to get an idea of what we will have in store.
