Katie Derham is back in action for the first night of the 119th season (yes, it really has been around that long) of one of the UK's most popular classical events at the Royal Albert Hall. Tonight's theme is sea-inspired, with music from English composes Vaughan Williams and Britten. There are also two sets of Paganini variations by Rachmaninov and Lutoslawski and the world premiere of Julian Anderson's Harmony. Sit back, relax and enjoy after a long day in the sun.
