Barcelona's most spectacular concert hall is a Moderniste masterpiece, largely regarded as Domènech i Montaner's best work, just off the bustling Via Laitana. Performances run year-round. While the focus is generally on classical (the Palau de la Música Catalana is the historic home of the Orfeó Catalá, or Catalan Choir), major music festivals—such as Barcelona's Jazz Festival and even Sónar—generally have a date or two on the Palau's magnificently ornate stage. A sensitive extension to the original building by local architect Oscar Tusquets accommodates the Petit Palau, a smaller venue for recitals and shows for children. Tickets for most classical and family concerts can be bought at the box office, where you can also book a guided tour of the building.
