It’s somewhere around 7 years behind schedule, but Hamburg’s Elbphilharmonie concert hall opened its doors this week for its first ever public performance. Designed by Herzog & de Meuron, it was initially scheduled to open in 2010 at a cost of €77m. Instead it cost €789m and its first performance was, well, this week. This is according to The Spaces.

If by chance you didn’t attend the official opening ceremony (and even if you did), I recommend you check out this interactive drone fly through. It’s a neat (and potentially transformative) way to see the building, experience its architecture, and understand its setting on Hamburg’s harbor. Make sure you turn on your sound. It is a concert hall, after all.
