The Sloe Fair is a travelling funfair that is held annually on 20 October at Northgate carpark in Chichester, West Sussex.
 The fair was first held in 1107 or 1108 after King Henry I of the Kingdom of England granted Ralph de Luffa, Bishop of Chichester, the right to hold a fair for a period of eight days from a date of de Luffa's choosing.
 The fair was originally chosen to coincide with the Feast of Saint Faith the Virgin on 6 October, a Gallo-Romano saint with a strong following in the area, but in 1207 a license was awarded for the fair to be held several days later, on the Vigil of the Feast of the Holy Trinity and the eight days thereafter.
 It is, however, unclear whether the date of the fair was actually changed, and according to records held in the library of Chichester Cathedral, as late as the 18th Century the Court of Piepowders that was held on the occasion of the fair took place between the Feast of Saint Faith and the Eve of Saint Edward the Confessor, on 12 October.
 The name "Sloe Fair" is believed to be a reference to a sloe tree that grew on the original site of the fair, in a field just outside Chichester's North Gate.

 Its origins go back to 1917, when Leifs was just 18, and was completed in 1930.
 It is an uncompromisingly dark work somewhat linked to medieval music, with influences from the tvísöngur tradition in a dissonant triadic context.
 It lasts about 21 minutes, and contains three movements, with a short introduction and finale framing a much longer Passacaglia consisting in thirty variations.
 Its theme comprises the total chromatic, critic Alex Ross described as "Bach walking in the tundra".

An organ concerto is a piece of music, an instrumental concerto for a pipe organ soloist with an orchestra.
 The form first evolves in the 18th century, when composers including Antonio Vivaldi, Johann Sebastian Bach and George Frideric Handel wrote organ concertos with small orchestras, and with solo parts which rarely call for the organ pedal board.
 During the Classical period the organ concerto became popular in many places, especially in Bavaria, Austria and Bohemia (whether called there a concerto, pastorella, or sonata), reaching a position of being almost an integral part of the church music tradition of "jubilus" character.
 From the Romantic era fewer works are known.
 Finally, there are some 20th- and 21st-century examples, of which the concerto by Francis Poulenc has entered the basic repertoire, and is quite frequently played.
