The Boston Symphony Orchestra has had a change of heart regarding its recent decision to hike the prices of some tickets at Symphony Hall by as much as 80%, after hearing from hundreds of angry subscribers. High ticket prices have become a way of life for major American orchestras, and the BSO’s are some of the highest in the industry, but in the process of reassessing its pricing scale, the orchestra had decided that a batch of seats in the second balcony had been dramatically underpriced, and hiked the per-concert price from $57 to $83. After weeks of protest and the launching of a web site excoriating the price hikes, the BSO announced that it will offer subscribers some relief from the new prices.
