Home to the Helsinki Philharmonic Orchestra, Finnish Radio Symphony Orchestra and Sibelius Academy, the glass- and copper-fronted Helsinki Music Centre, opened in 2011, hosts a diverse program of classical, jazz, folk, pop and rock. The 1704-capacity main auditorium, visible from the foyer, has stunning acoustics. Five smaller halls seat 140 to 400. Buy tickets at the door or from www.ticketmaster.fi.
The bar is a stylish place to hang out over a drink, and there's an excellent classical-music store here. Check the online agenda for regular guided tours (English available; free to €15).
