When the Bedichek Middle School Orchestra got on a bus Wednesday, the students all thought they were going to a small performance.

"I thought we were fundraising for our summer trip," 8th Grader River Seidel said.

But, when they walked onto Rainey Street into some of the busiest SXSW locations, they started realizing something was up.

"They had no idea," StubHub Spokesperson Jessica Eskine said. "They didn't know what they were here for."

Erskine made a presentation to the students on behalf of StubHub and the Mr. Holland's Opus Foundation. The two groups have made a three-year pledge, including a $3 million grant to help schools and musical programs across the country.

"Your school is receiving $22,000 in instruments for your program," Eskine told the students.

"It's a big deal. It's a really big deal," Bedichek Middle School Orchestra Director, Samantha Stewart said.

According to Stewart, Bedichek is a Title 1 school and when it comes to the orchestra, "almost 99% of my students rent instruments," she said.

The grant by StubHub came in the form of seven violas, two cellos and more. Not to mention the private concert the students got with band "Jukebox the Ghost" -- all leading up to surprise number two.

StubHub took over Bangers on Rainey Street and worked all day Wednesday to set up their branded stage. To officially kick off days of concerts at the venue, they invited the Bedichek Middle School Orchestra to be the first band to perform.
