The Henry Wood Promenade Concerts are more commonly known as "The Proms". Usually held at the Royal Albert Hall, these performances of classical music have an informal atmosphere and music lovers pack the stands every year. The Last Night of The Proms is world famous and it is extremely difficult to get tickets for that night. Tickets are by lottery and in order to qualify, you must have attended at least six other concerts during the season. Because the Last Night is inaccessible to most people, Hyde Park now hosts an open-air concert on the same night with tickets available to the general public. Performance times vary.
