Next month's Bass 2012 convention in Copenhagen will include a combined art event and concert featuring at least 100 double bassists.

Inspired by an 1801 naval engagement in which a British fleet led by Nelson defeated the Danish fleet, the 'Battle of Copenhagen' on 17 August will see the bassists joined by dancers, floating fire-art installations, historic ships and cannons.

The double bassists involved will rehearse specially composed music for the event during the convention.
