When our new friends here in Santiago get excited about the nightlife, Tony and I can only nod supportively. We’re unlikely to ever see the other side of midnight again. And yet, this extrovert’s need for belonging sometimes leads to unexpected choices, like saying “yes!” to a cello concert.
Starting at 9 p.m.
On a Wednesday.

The invitation came from one of Tony’s colleagues, Michelle, who is one of our favorite peeps here. We just couldn’t say no.

Tony and I arrived at Teatro Caupolican about 10 minutes early. The line snaked down the block. Surely these were people waiting to buy tickets, I thought. I confidently pulled Tony out of the line and up to another entrance, where we were told to get back in the line. Slowly, we inched our way inside and up to our seats, which were the equivalent of plastic folding chairs bolted to the concrete floor. The concert had already started. Gentle classical music wafted up from the stage, where Luka Šulić and Stjepan Hauser sat in the spotlight with their cellos.

Michelle and her posse soon appeared, although we didn’t get a chance to say more than a quick hello before the concert took a turn for the crazy.

I had seen this YouTube video of the duo – known as 2Cellos – and expected their music to be a little edgy.

But I hadn’t properly researched them. I was unprepared for the crowd to rush the stage at the first notes of “You Shook Me All Night Long,” and I hadn’t anticipated the strobe lights or strap-on electric cello that enabled Hauser to continue rocking out while he danced across the stage in blinking red devil horns. One lady tossed her cardigan on the stage, which Šulić grabbed and swung overhead sexily. Tame for a rock concert, maybe, but I would bet few cellists can claim such displays of adulation.

When the house lights came up between songs, we could see the 4,500-seat theater was packed.

Fans waved their phones the way we used to wave lighters, almost in a trance to the beat of the music. Women screamed and shouted, “I love you!” At one point, there was a chant that reverberated through the crowd. “What are they saying?” I asked my seat mate, Kristen. She didn’t know either, but we soon discovered it was a plea for a particular song, and the cellists responded. The crowd went wild.

2Cellos interspersed their playlist with a few classical pieces, but they mostly stuck with rock favorites by AC/DC, Michael Jackson, Guns N’ Roses, U2, Nirvana and Sting.

I had wrongly assumed the two guys were brothers. According to a November 2014 interview in The Strad, the two Croatian cellists met when they were about 14.

“When we were in Croatia, the people following our careers considered us to be big rivals,” says Hauser. “We were always great friends though – as soon as we met we felt a strong kind of camaraderie. There’s still some rivalry, but in a healthy way: we push each other to be better and better. On stage we make each other play to a higher standard.”

The duo’s website, 2Cellos, says their 2011 YouTube rendition of Michael Jackson’s “Smooth Criminal” opened the door to fame. They scored a record deal with Sony MasterWorks and an invitation to tour with Sir Elton John, who says in a video testimonial: “I was absolutely astonished! I said, oh my God, I’ve never seen cello players play like this. I’ve never seen cello players rock out. And I said, God, I’ve got to have them in my band straight away.”

The show was incredible, totally worth staying out late on a school night.
