Sam Shepherd and Genene Blackwell have been friends since they were kids.

They later bonded over their mutual love of music, which led them to form the duo InnerVision.

The name has significance because both Shepherd and Blackwell are blind.

"It's kind of like, we are blind, we physically can't see, but we can see through the heart, we can see inwardly more," Shepherd said.

InnerVision will close out the Sunday concert series in German Village. The show is slated for 6:30 p.m. Sunday, Sept. 17, in Frank Fetch Park.

It is free and open to the public.

Shepherd said the show will focus mostly on blues, soul and gospel.

He sings, plays guitar, trombone and harmonica. Blackwell is the keyboard player.

They were inspired by musicians such as Ray Charles, Stevie Wonder, Elvis Presley and Frank Sinatra, Shepherd said.

"We have some of the weirdest, most scattered set lists ever," he said. "It's a pretty creative kind of thing."

Both of the musicians, who are 26 years old, were born with retinopathy, a disease of the retina that can lead to vision loss or total blindness. Shepherd said he can make out the differences between light and dark but cannot see shapes. His bandmate has been blind since birth, he said.

They have been together for eight years, mostly playing at festivals, senior centers and retirement homes, Shepherd said.

He said being blind has given him perspective. People might look at it as an obstacle but he said he doesn't feel that way.

"It's really been a blessing to me, but there are roadblocks here and there from time to time," he said.

If it rains Sunday, the concert will be moved to the German Village Meeting Haus, 588 S. Third St.

Ashleigh Lemon, vice president of the German Village Garten Club, which sponsors the concerts, said InnerVision is poised to end the concert series on a high note.

"They play so many different types of music, and their story alone is one that makes you want to come listen to them," Lemon said.

"I am very excited to have them for our last concert in the park."
