A few years back, the Edinburgh International Festival sought to recapture some of the crowds and attention which had been diverted to the hugely popular Edinburgh Fringe by creating a new late-night concert series featuring some of the world’s finest classical musicians, with all tickets priced at a rock-bottom £5. The idea was to try to draw new audiences who ordinarily wouldn’t have come near the concert hall. Instead, while the Festival’s existing audience found the £5 admission attractive, no one else seemed to much care. So this year, the Festival is pulling the series altogether, claiming that it had the opposite effect on ticket revenue from what was intended.
