All four members of the band from Warrington, U.K. died along with their band manager Craig Tarry, 32, in the crash in Sweden, and their families are confident the release of the album will be the ultimate tribute.

"We are tremendously proud of everything the boys achieved in such a short space of time," a statement from the families reads.

"Craig, Jack, Kris, River and Tom shared a huge passion, talent and dedication to music. We believe the best way to celebrate our sons' lives is to release an album of their songs."

"This is their legacy and we know deep in our hearts that the boys would want the world to listen to the music they poured everything into," the statement continues. "This was only the beginning for them and these nine songs were written with every intention to be shared, heard and, most of all, enjoyed.

"We hope that it brings you as much happiness listening to it as we know it did to them making it."

The self-titled release will hit stores on 29 July (16).
