HAMBURG.- Germany late Wednesday premiered a spectacular new concert house in Hamburg to the strains of Beethoven and Wagner that has been touted as a new global attraction, albeit after a cost explosion.

Chancellor Angela Merkel and President Joachim Gauck joined 2,100 guests at the inaugural concert under tight security in the grand hall of the Elbphilharmonie, which has electrified critics with its audacious design and world-class acoustics.

The three-hour-long programme met with a lengthy standing ovation.

Billed as a cultural monument ready to rival the Sydney Opera House, the building came in more than six years overdue and at 10 times the initial budget, with a cost to the venerable northern port city of 789 million euros ($829 million).

Gauck said he was "awed" by the "incredibly beautiful" architecture and its "wonderful sound" but acknowledged its turbulent beginnings.

"The Elbphilharmonie has been called a dream and a nightmare, a global star and a joke, an embarrassment and a wonder," he said.

But the enormous project's success would come from "the magic of its contrasts".

"The Elbphilharmonie can become what many people in Hamburg hope for: the symbol of a cosmopolitan metropolis that is open to the world, and a jewel in the crown of Germany as a nation of culture."

Merkel later told NDR public television the night had been historic.

"One day we will all be very proud that something was built in our time that people will still refer to in 50 or 100 years, saying 'look, that was what happened on January 11, 2017'."

'Difficult birth'
Jutting out from the city at the end of a pier on the Elbe River, the Elbphilharmonie has a boxy brick former cocoa warehouse as its base, with a breathtaking glass structure recalling frozen waves perched on top.

Sandwiched between the two levels, a public plaza protected by giant curved glass windows offers stunning views of the harbour, the spires of the charming old trade centre and Hamburg's temperamental skies.

Earlier Mayor Olaf Scholz defended the project, saying that its sold-out concerts through July and the more than 500,000 visitors who have already flocked to the building proved the Elbphilharmonie was winning hearts.

"It was a difficult birth but they have adopted the child," he said of the 1.7 million residents of Germany's second city who have footed the bill.

Scholz insisted that the Elphie, as the two-hall concert house has been nicknamed, would be a building for the people, with diverse events appealing to visitors beyond the well-heeled classical music set.

"It is my aim that every pupil in a Hamburg school will see a concert here," he said.

Scholz said the building would embrace the long musical tradition of Hamburg, the birthplace of Brahms and Mendelssohn and the cradle of the Beatles' early stardom, and soon host concerts by the world's top orchestras.

Musical director Christoph Lieben-Seutter promised eclectic programming, including a series of concerts featuring Syrian music in the spring honouring the thousands of asylum seekers who have arrived in the city.

The Elbphilharmonie's completion marks a rare urban development success story in Germany, which has been plagued by planning disasters such as Berlin's international airport, now five years behind schedule and counting.

To claw back some of the investment, Swiss architects Jacques Herzog and Pierre de Meuron, who also designed Beijing's "bird's nest" Olympic stadium and the Tate Modern gallery in London, added posh apartments, restaurants and a luxury hotel complete with an in-house meditation consultant.

The evening was designed as a showcase of Germany's soft power through high culture, and spotlighted the acoustic potential of the hall's "vineyard" layout with seats stretching up in steep terraces from the stage.

The programme, kept secret until the opening, spanned 400 years of music history, including orchestral works by Beethoven, Wagner, Brahms and Mendelssohn and contemporary German composer Wolfgang Rihm.

For those not lucky enough to snag tickets for opening night, a light show on the Elbphilharmonie's glittering facade entertained crowds gathered outside in wintry weather.
