Blessthefall have completed their fourth album To Those Left Behind, which has been set for a Sept. 18 release via Fearless Records. Check out a teaser video for the album above.

"As a band we are constantly trying to outdo ourselves and take a step forward with each record," says lead vocalist Beau Bokan. "With this new album we've taken a giant f--king leap forward and are at our absolute best as musicians and song writers. We're looking forward to seeing where this album will take us."

The band once again worked with Joey Sturgis (Asking AlexandriaOf Mice & Men), who produced their 2013 album Hollow Bodies. It was their most successful album to date, debuting at No. 15 on the Billboard 200 album chart.

Before the album drops, Blessthefall will spend their summer on Warped Tour, which kicks off June 19 in Pomona, Calif. There are a lot of metal and hard rock bands on this year's lineup, including Black Veil Brides, Asking Alexandria, Escape the Fate, Miss May I, Senses Fail, Silverstein, Memphis May Fire, August Burns Red, Attila, The Amity Affliction, Beartooth and more.
