The band, whose last studio album was 2001's Rock Steady, revealed the news in a video posted on their newly updated website.
"We hope you like the new video and the big news," a statement on their website read. "We are incredibly excited to share the new music with you. Ear candy coming your way!
"We thought the big release date announcement and video deserved some new photos as well. We will debut a fresh new site and artwork closer to the album release but wanted to add some new photos in the meantime.
"Thank you all so much for your support over the last 25 years. We're really proud of our new album and we hope you love it as much as we do.
"We'll be posting a lot of updates between now and September as we shoot the video and start rehearsing to perform the new songs live for all of you."
