Classical music fans will be able to see the Ocean Sun Festival at sea, when it returns on board the Europa this year.
It will be the second time the line hosts the musical, following its first appearance on the Europa in 2012.
Ocean Sun will turn the cruise ship into a festival stage as it travels on its 13-day cruise from Travemuende, Germany to Hamburg, Germany from 31 August to 13 September 2014.
This year, classical artists include pianist Alexander Krichel, violist Nils Monkemeyer, soprano singer, Anna Prohaska, pianist Lauma Skide and the musicians in the David Orlowsky trio.
In addition to the concert, cruisers will also be able to experience sites and cultures as the ship makes calls in Goeteborg, Oslo, Greenwich, Honfleur, Antwerp and Amsterdam.
