Size-wise the Karl Marx puts other Havana theaters in the shade with a seating capacity of 5500 in a single auditorium. The very biggest events happen here, such as the closing galas for the jazz and film festivals and rare concerts by trovadores like Silvio Rodríguez. In 2001 it hosted Welsh rockers the Manic Street Preachers, the first Western rock band to play live on the island (with Fidel Castro in the audience).
