There are 3,000 seats in the Orange County Performing Arts Center's Segerstrom Hall, in the orchestra level and the three upper tiers. So-called Premier Boxes are separated in an area in front of the first tier and in two sections jutting forward from the upper tiers. Prices for Premier Box seats will range between $100 and $200 per performance. Orchestral-level seats will cost between $30 and $150; Tier 1, $20 to $150; Tier 2, $15 to $135; Tier 3, $7 to $105. Prices depend on such variables as proximity to stage and on the attraction. Tickets will generally be sold as subscription series of four or more performances.
