Casa da Música do Porto (House of Music), by Rem Koolhas, 2001-2005 - in Porto, Portugal
It houses the cultural institution of the same name with its three orchestras Orquestra Nacional do- Porto, Orquestra Barroca and Remix Ensemble.
The New York Times, classified it as the "most attractive project the architect Rem Koolhaas has ever built” and saying it’s "a building whose intellectual ardor is matched by its sensual beauty". He also compares it to the “exuberant design” in Frank Gehry's Guggenheim Museum in Bilbao, Spain. “Only looking into the original aspect of the building, this is one of the most important concert halls built in the last 100 years”
