This will be the most-watched symphony video of 2014

This is the Seattle Symphony letting its hair down at the weekend with conductor Ludovic Morlot and rapper, Sir Mix-A-Lot.

More than half a million people have viewed this video in two days. No other orchestra has anything half as viral.

However – you knew there was a however coming – this performance is a about men’s commodification of women’s bodies. It is lewd, rude, sexist and demeaning. If you don’t think so on first hearing, imagine he is singing about you or one of your loved ones.

None of the players in the orchestra smiles at the DJ’s lines or even looks up when he mentions them. UPDATE: Though we gather that the concert was attended by conference members of the League of American Orchestra, some of whom danced on stage (do shout if you recognise any of them).

This is not, in our view, something a symphony orchestra ought to be doing. Let Sir Mix peddle his rap somewhere else. Let Seattle promote itself on art rather than sell its orchestra to a sexist rant.
