The Renée and Henry Segerstrom Concert Hall stands as a architectural masterpiece within the Segerstrom Center for the Arts in Costa Mesa, designed by Cesar Pelli with acoustics engineered by Artec Consultants. Opened in 2006 at a cost of $265 million, this 1,704-seat shoebox-style concert hall boasts unparalleled sound quality thanks to advanced features like adjustable acoustic canopies in silver leaf, movable reverberation chambers, and blond maple wood paneling. Home to the Pacific Symphony, Philharmonic Society of Orange County, and Pacific Chorale, it hosts jazz, pop, opera, classical concerts, and luminaries such as Yo-Yo Ma and Tony Bennett. Its multi-tiered foyer dazzles with a circular marble staircase, silver-leaf ceiling, and a 'Constellation' lighting installation of 300 Baccarat crystal pendants, offering views across the 46,000-square-foot plaza to Richard Serra's towering 'Connector' sculpture. Seating spans orchestra, loge, grand tier, founders tier, intimate box seats, and choral terrace behind the stage for unique perspectives. The venue's NC-1 acoustic isolation and the magnificent William J. Gillespie Concert Organ with 4,322 pipes elevate every performance in this elegant South Coast Plaza neighborhood setting. Patrons enjoy on-site amenities like Leatherby's Cafe Rouge and a dedicated box office, creating an immersive atmosphere centered on sonic excellence and cultural prestige.
