Kris Leonard, 20, River Reeves,19, Tomas Lowe, 27, Jack Dakin, 19, and their manager, Craig Tarry, 32, perished in February (16) when their vehicle fell off a bridge more than 80 feet into a canal near Stockholm.

The band were in the country to play their first gig outside the U.K., at the Where's The Music? festival in Norrkoping.

The eponymous album, compiled by their families, went on sale on Friday (29Jul16).

A statement from the bandmembers' families on the release of the album reads, “We are tremendously proud of everything the boys achieved in such a short space of time.

"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."

Producer Ian Grimble, who helped the families put together the album, revealed to Britain's NME magazine that it was a difficult process due to hearing the boys' voices again on the material they'd recorded

"The process of putting it together was hardcore," he explains. "The hardest part was going through the session where they'd very quickly thrown down every song they had, so there were a lot of stops and mistakes and general mucking about - that was difficult to listen to. But by the time we'd finished recording, we had it exactly how they wanted it to sound - they were happy with every note."

Negin Karimi, the girlfriend of Kris, tells the magazine that although she finds the record tough to listen to, she enjoys it because its what her boyfriend would have wanted.

“Some of the songs on the album I find harder to listen to than others," she says. "But we have to train ourselves to make it a positive thing, because this isn’t an album that should make people sad – they wrote songs to make people happy.

"I always think, ‘What would Kris say?’ And I know Kris would tell me to man up, put a smile on my face and enjoy the music.”

Like their debut single Swings and Waterslides, which reached the Top 10 of the U.K. chart in the wake of their deaths, Viola Beach is released on the band's own record label, Fuller Beans.
