Trent Reznor's side project How To Destroy Angels has scrapped two upcoming festival appearances due to "production conflicts".

The Nine Inch Nails star formed the group with his wife Mariqueen Maandig and musical partner Atticus Ross in 2011, and they booked just two dates this autumn (13), performing for fans at the Mountain Oasis Electronic Music Summit in North Carolina next month (Oct13) and the Voodoo Experience in New Orleans, Louisiana in November (13).

However, Maandig has now revealed both shows have since been axed.

In a series of posts, she writes, "We're very sorry to announce that due to unforeseen production conflicts Destroy Angels will be unable to perform at Voodoo & Mountain Oasis (sic)... Our sincerest apologies for the inconvenience, we tried everything to make it work. We will be back."

She did not specify the problems preventing their performances, but Reznor is still due to hit the stage at both events with his Nine Inch Nails bandmates.
