A very substantial number of artistic events in the UK would never take place without commercial sponsorship, and IBM UK is in the forefront of commercial sponsors: this year’s highlights include a return to Glyndebourne to help fund Ravel’s L’Enfant et les Sortiges and L’Heure Espagnole; it is also backing productions of The Trojans by the Welsh National Opera and by Opera North; the London City Ballet’s staging of Giselle; and the London Sinfonietta’s 1987 season.
