[Kohlsdorf] Since 2009, music bands have ventured the outskirts of Maquoketa where they park their cars, board an old school bus and disappear down a winding gravel road.

Their destination, Codfish Hollow Barnstormers, a concert venue unlike any other.

♪♪ [Tiffany Biehl] My grandpa built this barn in 1954.

And we host concerts.

There's free camping.

Kind of like a little mini festival.

♪♪ [Jen Hazer] First off, the barn itself, and it's just the atmosphere.

I mean, I've talked to so many people that the word they use to describe it is magical, and it is.

Codfish Hollow!

(crowd cheering) ♪♪ [Tiffany Biehl] The first show we didn't have a stage.

We didn't have a sound booth.

We didn't have any of that.

We didn't think we might ever do it again until it happened and then we were like, that was very awesome, let's keep doing this.

[Kohlsdorf] Owner Tiffany Biehl and her husband Shawn had no background in music promotion before booking their first barn concert.

But they built it, and the people came.

[Tiffany Biehl] In the beginning it was just get all the hay and the cows out of the barn so that we could have our first concert.

Bands had a good enough time here that they told their friends and their friends told their friends and then they just started coming.

[Rob Goerg] This is probably my fifth time, maybe sixth time here.

I mean, this place is like one in a million.

There's no other place like this in the whole world.

[Kohlsdorf] As word of mouth spread, this little barn outside of Maquoketa began to attract some very big names.

[John Rushton] It's fun to see people who have never been here before come and just look and see all of the signs that are up on the ceiling.

Nathaniel Rateliff & the Night Sweats, Dawes, Counting Crows have been here, Norah Jones has been here.

So many other bands that you might not necessarily hear about on mainstream radio are here.

♪♪ [Robert Siegwarth] It's a challenge sometimes because it's a barn.

There's no heat or air conditioning, so basically, we have to load in, load out every show.

Share the barn with a lot of critters, mice and birds and you can even hear them in the background.

Our goal is to make the best possible sound for everybody in here, for the bands, for the patrons, for everyone.

♪♪ [Tiffany Biehl] We just give the bands everything that we have out here.

I basically hand my house over to them and tell them the house is yours, except we started now that we're old enough, or older, we keep our own bedroom, my husband and I.

But in the olden days we gave that up too and slept on the floor.

But we give them lunch, supper, bands will stay overnight in the house and then we cook them breakfast before they're on their way the next day.

This is definitely the coolest place I've ever played.

(crowd cheering) ♪♪ [Robert Siegwarth] I heard one of our more veteran bands telling a band that was opening for them that had never been here before that Codfish was a destination venue and that you might come play here just so you get to come spend the day here.

And I thought that was like a huge compliment.
