Chart-topping Recording Artists Jack & Jack to help launch Shuttersong, the free mobile app for connecting photos with sound.

Billboard chart topping stars, Jack & Jack will kick off the partnership with a contest for a fan to win a chance to see them perform live in concert.

"We're always looking for exciting new ways to connect with our fans and Shuttersong is another way to do that," said Jack & Jack. They will make Shuttersongs to celebrate the release of their new EP, Calibraska, which has trended in the top 5 albums worldwide for five days straight.

Jack Johnson and Jack Gilinsky, collectively known as Jack & Jack, will announce the contest to their nearly 20 million and growing combined followers across social media. Shuttersong is a digital community where you can create and share "Shuttersongs" - photos that have music, sound or voice embedded into them.

"There's something powerful that happens when music and still images combine, and we're excited to see how creative Jack & Jack's fans will get with this new medium and channel.  They can engage with Jack & Jack and with fellow Shuttersong users," said William Agush, founder, inventor and CEO of Shuttersong.

"The Shuttersong app is already incredibly popular with teens, musicians and artists so this really is the perfect match."

Jack & Jack will be announcing a contest for fans to win a chance to see them live and to get involved with Shuttersong via their Twitter and Instagram accounts in early August. 

Shuttersong is a free mobile app for connecting photos with sound.

"Our goal with the new Shuttersong was to connect likeminded people who love to share photos with each other so they can discover other people with similar interests," said William Agush, founder, inventor and CEO of Shuttersong.

"There are so many great Shuttersongs being made every day on the app, the next step for us was to let them be shared with each other and for others to join as a way to share their special moments in a cool, high-quality way."
