Organisers of the first Alt-Fest music event have been blasted by an Italian rock band for refusing to confirm or deny reports it will be cancelled.

Ticketholders began to worry the inaugural British heavy metal festival would be called off when rocker Marilyn Manson announced it was cancelled on his online schedule. Gary Numan and Cradle Of Filth have also reported their set is not going ahead.

The organisers apologised for the delay in addressing rumours on the event's Facebook.com page and revealed they were struggling with many issues so could neither confirm nor deny reports.

They wrote on Wednesday (30Jul14), "We at Alt-Fest HQ would like to sincerely apologise for our silence over the last 24 hours. Currently we are working all hours to deal with some extremely challenging & stressful issues for Alt-Fest. We will be able to provide an official statement with full information before Monday and answer any questions you may have at that time."

Italian electronic group XP8 now blasted the organisers for keeping the bands who are on the bill in the dark too.

They commented on Facebook, "Are you going to contact us anytime soon or will you keep to (sic) ignore our email, and keep treating us as a 'B series' band while most of the headliners have been notified already yesterday? This statement was needed yesterday, and today you were expected to come up with a Proper solution, after having contacted privately all those bands who still haven't jumped ship. It's really time you learn you (sic) jobs."

The festival, created by $102,000 (£60,000) worth of donations on a crowdfunding site, was due to take place on 15-17 August (14) in Northamptonshire, England.
