The phrase "classical music" and the word "kegger" aren't usually in the same sentence together. But, they'll be in the same room Saturday night when musical director Nathan Felix puts on the Classical Music Kegger concert.

"My goal was simply to present classical music to an audience that wasn't used to to going to the concert hall or doesn't really know anything about classical music," Felix said.

He hopes donated kegs of Alamo Beer Company and Ranger Creek suds do the trick. In fact, donations have been key in putting this concert together.

"The community provides us with the pianos, we present the art, and then we give back to the community," Felix said.

The last part of that equation will come after the concert when the pianos will be donated to schools or organizations in need.

"I hopped on board in a heartbeat," said Lori Skinner, executive director of the Chamber Orchestra of San Antonio, referring to the piano she donated to the cause. "I just made sure I asked my daughter if she minded if we got rid of her piano that she doesn't play anymore."

The Chamber Orchestra partnered with Felix, an Austin native, to bring this concert to San Antonio after he put on a similar show in the capital city.

"Part of our mission is to create new audiences, and part of it is bringing millennials into it and helping them understand what the classical world is all about," Skinner said.

They're putting this event on at Renewable Republic at 1903 S. St Mary's. It's a communal work space with a vibe Skinner and Felix hope will resonate with their target audience.

"We hope people can come and feel that energy and think 'I can do something if we bring the right people in the community together,'" Felix said.

Once the concert is over, they'll work with local schools and organizations to coordinate delivery of the pianos. But they won't just sit there collecting dust. Felix plans on providing lessons on those pianos and showing kids they can have a future in professional music.

"You know, I had a lot of colleagues that gave up," he said. "I think because they didn't have the right people that showed them, 'hey, I can work as a musician. It's possible. Keep going.'"

The show and the beer are free, but Felix says they will be taking donations. Everything kicks off around 7:30 p.m.
