Carnegie Hall has been known for its impeccable acoustics but after a renovation in 1986, concert-goers swore that the sound was a bit off. And they were right! The culprit? A slab of concrete found underneath the stage nearly a decade later. "They opened stage floor, found the cement, took it away and the sound came back," said Gino Francesconi, director of Carnegie Hall's archives.

When you think about the famous acts who have graced Carnegie Hall -- George Gershwin, Leonard Bernstein, The Beatles, Bob Dylan, Judy Garland and Johnny Cash -- this New York City landmark clearly has plenty of stories to tell. To uncover some of its secrets, amNewYork went on an exclusive behind-the-scenes tour of the hall, from its lesser-known underground concert space to its new rooftop garden. Here are just some of the hidden gems and interesting stories we discovered about Andrew Carnegie's world-renowned "Music Hall," which came extremely close to being demolished.

The singer holds the record for most consecutive sold-out performances (17) at the hall, according to Gino Francesconi, Carnegie's director of archives. Minnelli first made her debut at Carnegie in 1979, setting a record with 10 sold-out performances, but in June 1987 she beat her own record and this one remains unbroken. (During one of Minnelli's Carnegie engagements, a then-20-year-old Francesconi said he was pulled into working the bar that night and Liza's father taught him the proper way to make a rum and coke.)

Well, now you can look that up by using the "Performance History Search" tool via carnegiehall.org. The hall only started digitizing its huge collection of archival materials, which includes photographs, program books, posters and recordings, in July 2012, so the online database is not complete. But right now, you can search through records spanning between 1891 and 1955. Just type in a name of a performer or composer you want to find. Or for fun, see what happens when you type your own last name in. You could discover you had some talented ancestors.

It was added during the recent Studio Towers Renovation Project and opened in the fall of 2014. The hall uses the space to host receptions before and after some of its concerts. It's also a gathering space for performers, concertgoers, students, staff and teacher, and it's available for private events with rental of the Weill Terrace Room.

According to the hall's archivist Gino Francesconi, most of the drawings have been missing for quite some time. Credit: Tara Conry It was nearly demolished March 31, 1960 was supposed to be the day that Carnegie Hall was demolished. By then, Andrew Carnegie had passed away, and the hall had been sold to realtor Robert Simon, who then also died and left control of the venue to his son, Robert Jr. Struggling to keep the hall running, the younger Simon agreed to sell the building to developers who planned to raze it and erect a 44-story office tower on the site. A rendering of their plans was featured in a 1957 issue of Life magazine, pictured above. But in the 11th hour, a group called the Citizens Committee for Carnegie Hall, was able to stop the impending demolition. A few months later, as a result of special state legislation, New York City purchased Carnegie Hall for $5 million, and a new nonprofit called The Carnegie Hall Corporation was formed to run it.

Well, that's what the program read when the British group played Carnegie Hall on Feb. 12, 1964. Paul McCartney's first name had accidentally been changed to John, so when he autographed the program you can see he tried to cover up the area by signing directly over the misprint. The program is one of many artifacts on display inside Carnegie Hall's Rose Museum.

This extremely strong and durable rock type was formed about 450 million years ago and provides a solid foundation, according to the New York City Parks Department. To construct Carnegie, workers blasted through the bedrock with explosives, according to Francesconi, but that wasn't an option when carving out the Zankel concert hall. To expand the existing space, they had to take a slower and more careful approach, excavating 8,000 cubic yards of Manhattan schist and debris, "enough to fill 363 New York City garbage trucks," The New York Times reported.

And they were right! The culprit? A slab of concrete found underneath the stage nearly a decade later. "They opened stage floor, found the cement, took it away and the sound came back," said Gino Francesconi, director of Carnegie Hall's archives. Credit: Carnegie Hall Mrs. Carnegie's hall And while the hall is now named after Andrew Carnegie, it may be more appropriate to refer to it as Mrs. Carnegie's hall. It's believed that Carnegie, then a newlywed, built the music hall as a wedding gift to his wife, Louise Whitfield Carnegie, says Gino Francesconi, director of the hall's archives. Another fun fact: The couple signed one of America's first prenuptial agreements, he added. When Andrew died in 1919, he left his wife her personal assets, a small cash gift, their Manhattan townhouse and their holiday home in Scotland, Skibo Castle, Forbes reported. And she sold Carnegie Hall to a New York City realtor.

Many people don't realize there are two other performance spaces -- the 599-seat Zankel Hall (pictured), and the 268-seat Weill Recital Hall -- located inside Carnegie. Zankel is located beneath the Stern auditorium and Weill is practically next door to the main concert venue, but thanks to impeccable sound-proofing, performances can take place in all three spaces simultaneously without interfering with one another. Credit: Carnegie Hall Weddings for musical lovers If your shared love of music brought you together, perhaps a wedding at a world famous music hall is something you desire. Well, in that case you might be happy to hear that yes, Carnegie Hall does host wedding receptions thanks to the building's latest renovation. Weddings, as well as other catered private affairs, can be held inside one of three reception spaces including the Weill Terrace Room, pictured. It accommodates up to 250 people and is adjacent to the garden terrace.

Hidden within the architectural details are angels and devils. See how many you can spot. Credit: Carnegie Hall It wasn't always Carnegie Hall Carnegie Hall may be one of the most well-known New York City landmarks today, but for a few years, the venue went by a different name. When it opened in 1891, it was simply called "Music Hall." That's what the programs and even the sign outside the building read. It wasn't until the 1894-1895 season, that the hall's Board of Trustees rebranded it, naming it after its financier, Andrew Carnegie. Credit: Tara Conry The unlocked door What's the best way to see a sold-out act at Carnegie Hall? Well, if you were a student studying there you knew about this door, which leads to the balcony of the main hall. Up until the mid-1970s, Francesconi said this door was always unlocked and students would often duck out of class and sneak into rehearsals this way. Credit: Tara Conry The secret speakeasy To get into the underground nightclub adjacent to Carnegie Hall, you needed more than just an invitation or a password. Guests to Club Richman, which was dubbed "New York's smartest rendezvous," had to have their own special key. They would insert it into one of the keyholes on this lock while the doorman put his key into the other, and if both keys worked, you could go in. But when Andrew Carnegie's widow found out about the club, which functioned as a speakeasy, according to Gino Francesconi, director of Carnegie's archives, she wasn't happy. She filed a suit attempting to shut it down, but the club stayed open until the end of prohibition, he said. Actress Joan Crawford actually got her start dancing there, he added.

But Brando often could be found inside his neighbor's apartment, hiding out from his adoring fans, Francesconi said. To show his gratitude to her for providing him refuge, Brando sent the neighbor a dozen roses with this note attached: "In appreciation for courageous perseverance displayed in Hall Battling and neighborliness above and beyond the call of duty." He signed it "Not so Private Citizen, Marlon Brando." Previous Secret Next Secret Comments We're revamping our Comments section. Learn more and share your input.
