Glenn Donnellan, who plays for the National Symphony Orchestra, played a rendition of "The Star-Spangled Banner" on an electric violin that was made by a regulation bat, according to The New York Times. The anthem sounded like Jimi Hendrix's version of the same song played at Woodstock in 1969.
"Donnellan kind of made it his own," said Tom Davis, the Nationals' entertainment coordinator. "Everyone that I heard from -- even from today -- have been raving about it. It was the coolest thing, the greatest rendition.
"I know people who really want the traditional thing, and they are even coming out and saying, 'That guy was great. He was really something special. I love it.'"
Donnellan would later play the same violin in the bottom of fourth inning during the Presidents Race.
Davis hopes to bring Donnellan back to Nationals Park during the last homestand in late September.
