I'm in two minds about the Proms tradition of always allotting significant programming space to composers with major anniversaries. It's transparently a fairly arbitrary device to make the programmers' jobs much easier and minimise the thorny problem of personal taste entering the decision-making process; on the other hand, without it we would never get three concerts this year featuring one of my favourites, Percy Grainger (died 50 years ago). In particular, the late night Prom on 2 August including Kathryn Tickell and June Tabor, celebrating the folk music Grainger was inspired by, is to me one of the most interesting this year.
