Last year, The City of London Festival celebrated its fiftieth anniversary, but you can expect to party just as hard in 2013, because there is another celebration to be had. An even bigger one: the four hundredth anniversary of a special relationship between London and Derry, which formed the Irish city, Londonderry.
This has inspired several themed events, including At Sixes and Sevens, a newly commissioned choral and orchestral work that will be performed simultaneously in the Guildhalls of London and Derry on the 3rd July at 7.30pm. Tickets are £10-£20 and include work by Northern Irish poet, Paul Muldoon and the composer, Mark-Anthony Turnage, plus Mendelssohn's incidental music to Shakespeare's A Midsummer Night's Dream.
Meanwhile, Trees, Walls, Cities is a major new song cycle linking eight 'walled' cities, which have seen a history of conflict and resolution.
Looking beyond the music, there are plenty of educational events taking place. These include a lecture on Stravinsky and Britten (okay, not quite looking beyond the music), a lecture on diplomatic treaties, a Deustche Bank Art Tour, and a walk through 'The City At War and Peace'.
On the fun side of things, you can immerse yourself in Irish culture, see street performers, attend a honey fest, and watch open-air ballet
These events can more, will be running until 26th July. You can see the full schedule on their website.
