American heavy metal band W.A.S.P. has cancelled their scheduled performance at the Tons of Rock festival in Oslo next week, citing family reasons. The cancellation impacts the festival’s Saturday headlining slot. German heavy metal band Accept will replace W.A.S.P. on short notice, according to a festival press release. Festival director Jarle Kvåle expressed regret over the cancellation but highlighted the festival’s success in securing a replacement. This year’s Tons of Rock is a sold-out event, marking a first for the festival. Accept’s addition ensures the continuation of a strong lineup for attendees. The festival is expected to proceed as planned with the revised schedule.
