The legendary Carnegie Hall may not be the world's biggest concert hall, nor its grandest, but it's definitely one of the most acoustically blessed. Opera, jazz and folk greats feature in the Isaac Stern Auditorium, with edgier jazz, pop, classical and world music in the popular Zankel Hall. Intimate Weill Recital Hall hosts chamber music, debut performances and panel discussions.
From September to June, Carnegie Hall runs guided tours (adult/child $17/12) of the building, shedding light on the venue's storied history (these are walk-in, but subject to performance and rehearsal schedules, so check the website before heading in). There's also the Rose Museum, which explores the venue's illustrious history through archival treasures (open 11am to 4:30pm; closed late July to mid-September).
