Rem Koolhaas has built a new concert hall in Portugal. It’s a building that challenges the concert hall norms. “Koolhaas keeps his concert hall at arm’s length. Its pleasures — derived from the architect’s wry brand of invention when it comes to form-making, structure and circulation — are no less impressive for their unmistakable detachment. To sit in its auditorium, a hard-edged, hangar-like space, is to consider the question of whether music can sound lovely or fully resolved in a space that works so hard to avoid appearing that way architecturally.”
