On Saturday, Nov. 10, the Minneapolis group will come to Faith Lutheran Church to perform original songs, as well as covers of classic hymns.
"They're not 'come lately' and they're not small," said Faith Lutheran Rev. Lee Laaveg. "They've been really well received over the last two decades."
Laaveg described River's style as "folk rock," and noted that "all three are guitarists, though they do a little percussion, too."
"They're kind of bizarre and weird but they're good," Laaveg said.
Laaveg's history with the band began 30 years ago, when the group traveled around the country as part of a youth encounter team, performing concerts for youth members of the church.
"We've kept casually in touch for the last 25 years or so," Laaveg said.
River has performed in the area before, though they performed primarily in Okoboji.
In addition to the Saturday night performance, River will also lead worship on Sunday morning.
"It's going to be a fun weekend," Laaveg said.
He continued. "I'm hoping that Christians from all over the Spencer and northwest Iowa area will feel pleased to come and take in the concert."
Laaveg noted, however, that the concert is open to all members of the community.
"I hope that people who love good music, but who may not presently be connected to any church, come and enjoy good music," he said.
Preceding the concert is a soup supper, beginning at 5 p.m. The concert is free to attend, though there will be a free-will donation.
"If people want to make it an evening, they can come have a bowl of soup and then stay for the concert," Laaveg said.
The concert will begin at 7 p.m. Sunday morning's church service will begin at 9 a.m.
"I hope anybody comes, whether they can throw a dollar into the bucket or not, we don't care. We just want them to come and enjoy some good music," Laaveg said.
