Dierks Bentley fans in Annapolis, Md. got a huge surprise when the 'Say You Do' singer turned up for a pop-up street performance recently.

The star chose this particular town in part to honor his father's military service, since it is home to the U.S. Naval Academy. Bentley wrote much of his latest album, 'Riser,' after his father passed away in 2012.

The show was part of VEVO's GO Show series. In the video above, Bentley offers a special performance of 'I Hold On,' one of the 'Riser' album's key tracks.

"This town is really special, so we wanted to do our GO Show here," Bentley explains. "We popped in at a really old-school downtown spot. My dad was in the army and I always had a lot of respect for him and for folks in the military for putting their country before themselves, and that's exactly what this song is about."

'I Hold On' is nominated for Song of the Year at the upcoming 2014 CMA Awards, in which Bentley leads the male nominees with five. In addition to his nomination for 'I Hold On,' Bentley is nominated for Male Vocalist, Album, Single and Music Video of the Year.
