Among the Coldstream Guard's duties is the famous changing of the guard ceremony at Buckingham Palace where their reputation for precision marching has led to them being described as the 'Red Machine'. The music reflects the title and heritage of this fine group; from the aggressive, machine-type music of the opening, the contrasting nostalgic French-flavoured waltz through the recapitulation and vivace finale. Listeners may hear references to music associated with the band, from Holst (the Planets) through the opening phrase of the chorale Ein Feste Burg - familiar to British Guards Bands from the troop march Huguenots.
