By now, you may have heard about the new Broadway musical Hamilton. When it opened off-Broadway in February, it earned almost unanimous raves and awards for blending history and hip-hop. Its sold-out run had A-list celebrities and politicians clamoring for tickets. Thursday night, the story of Alexander Hamilton, and the Founding Fathers and Mothers, opened on Broadway.

Broadway is New York's biggest tourist attraction and brought in $1.3 billion in ticket sales last season. But it's also a high-stakes gamble for producers, since only 1 in 4 Broadway shows turns a profit. This month, two of the fall's most highly anticipated musicals, a revival of Side Show and The Last Ship, with songs by Sting, have thrown in the towel — closing, having lost almost their entire investments.

New York is saying goodbye to another historic building. Steinway Hall, the main showroom for Steinway & Sons pianos, will be moving to a new location, leaving its home of almost 90 years on 57th Street near Carnegie Hall. The first floor has been designated a landmark and will be preserved, while the rest of the building will be torn down to build high-rise luxury condominiums.

Peter Brook is truly the grand old man of world theater. He became famous with his productions at the Royal Shakespeare Company in the early 1960s; wrote the seminal theater text The Empty Space; and started the International Centre for Theatre Research in Paris, where he developed such plays as the nine-hour adaptation of the Sanskrit epic, The Mahabharata.

Now, at the age of 89, Brook has brought his company to Brooklyn with a new play all about the mysteries of the human brain.

Sometimes good things come in small packages. Nonesuch Records, which started as a tiny independent budget classical label in 1964, is celebrating its 50th anniversary with three weeks of concerts at the Brooklyn Academy of Music. The label became a force in the recording industry by pioneering electronic music and world music, launching the ragtime revival and becoming a place where contemporary classical composers had a home. Now an industry powerhouse, Nonesuch still operates like an independent record company.

A labor crisis threatening to shut down New York's Metropolitan Opera — the largest opera house in the world — appears to have been averted. Two of the major unions announced a tentative settlement this morning. While agreements with 10 additional unions need to be reached by Tuesday night, this represents a major turning point in a bitter dispute.

The clock is ticking for the Metropolitan Opera in New York. The world's largest opera company may be headed for a shutdown. Most of the union contracts for the Met expire in a week. Yesterday, Met General Manager Peter Gelb sent a letter to the unions, warning them to prepare for a lockout if they don't come to terms.

For months now, the company and its unions have been at an impasse. Management has proposed cutting 16 percent of union members' compensation. Otherwise, Gelb contends, the company could go bankrupt in two to three years.

Most people who attend symphony performances can spot the concertmaster. That's the first chair violinist who enters before the conductor and helps tune the orchestra. But the all important position calls for much more than that — from playing tricky solos to shaping the sound of the string section.

Disney's animated film Frozen has been racking up impressive statistics since it was released last November. Its box office earnings total $1 billion, worldwide, the movie won two Academy Awards, and on the first day the home video came out, it sold 3.2 million copies. But one stat has taken both Disney and industry analysts by surprise: The soundtrack has become a phenomenon, topping the Billboard 200 chart 13 times.

Regardless of how critics and audiences eventually responded, Spider-Man: Turn Off the Dark was always going to be one of the most-discussed shows in Broadway history. It had songs by U2's Bono and the Edge; it was directed by The Lion King's Julie Taymor; it was based on a hit Marvel franchise; there were going to be flying stunts right over the audience's heads.

And then somehow it all went very wrong, from injured actors to huge cost overruns.

For 160 years, the pianos made by Steinway & Sons have been considered the finest in the world. So when hedge fund billionaire John Paulson recently bought the company, it struck fear in the hearts of musicians: Would the famously handcrafted pianos be changed, for the sake of efficiency? Paulson, who owns several Steinways himself, says nothing will change.
