Decapitated have just cancelled three festival appearances because of a "a full blown tour" across the US as the main support act.
If it's this, then it will run into at least early June, as two of the appearances they've cancelled were in the first week of June.
30/7 King Diamond
1-2/8 BiesenRock Festival
3/8 Lokerse Festival
16/9 Richie Kotzen
