If anything is to be expected from the Shaw brothers, it's the unexpected.
Andy Shaw, who performs with his brother, Chris, said their upcoming show in German Village would include nearly all original numbers representing a multitude of genres, including reggae.
"We're kind of weird people," Andy Shaw said. "It's hard to pin us down. We love all kinds of music."
The Shaw brothers will perform at 7 p.m. Sunday, Aug. 20, at Frank Fetch Park as part of the Third Sunday concert series.
The concert is free and open to the public.
Andy Shaw plays guitar, and Chris Shaw plays violin and, on some songs, guitar.
"We call it emotionally driven folk music," Andy Shaw said.
He said they have a natural symbiosis and have fun entertaining each other and the crowd.
"We've been doing music since we were both kids," Andy Shaw said. "Our dad is a retired music teacher.
"The songwriting thing is something we both started doing right after high school."
And they both are in separate bands: Andy in the Andy Shaw Band, a reggae-rock and American-roots outfit, and Chris in Topher James & Biscuit Brigade, a classic soul group.
Playing Frank Fetch Park will be a new experience for the Shaws.
"We tend to play a lot of weddings and private events in the summertime to help us do what we do, but it's not necessarily a listening crowd," Andy Shaw said.
In the event of rain, the concert will be moved to the Meeting Haus, 588 S. Third St.
Ashleigh Lemon, a member of the German Village Garten Club, one of the sponsors of the concert series, said the Shaw brothers put on quite a show.
"The sound that comes from just two people is incredible," Lemon said. "They are extremely talented and play multiple instruments."
