Lovers of all things jazz are spoiled for choice every November when the London Jazz Festival takes over the capital. The 10-day celebration sees large venues, from the Barbican and the Royal Festival Hall, to smaller clubs, such as Vortex and the redoubtable Ronnie Scott’s, sparkling with talent. This year’s headliners include Norwegian saxophone guru Jan Garbarek and Grammy-winning Brazilian pianist Eliane Elias. Alternative-country heroes Calexico, Chicago beat scientist Makaya McCraven and a live soundtrack to the 1925 Soviet classic Battleship Potemkin lend their strength, keeping the hip factor high.
