Swedish heavy metal stars Katatonia have axed an upcoming concert in North Carolina because of "logistical and financial difficulties".

The rockers were due to play The Soapbox in Wilmington on 7 May (13), but they have pulled the appearance after encountering unexpected problems.

A post on the band's Facebook.com page reads, "Due to logistical and financial difficulties, we're sorry to say we have no other choice but to cancel the gig at The Soapbox, Wilmington, North Carolina on May 7th. No other dates are affected."
