According to the Polish booking agency Massive Music, DEICIDE's previously announced European tour with VADER, which was scheduled to take place in October, has been pushed back to January 2009. The trek will last three weeks and will feature DEICIDE in the headlining slot and VADER as direct support. One more act will be added to the tour.
とありますが、恐らくEXTREME THE DOJO Vol.21はDEICIDEとVADERともう一つバンドを加えて行われるのかなと期待・・・。
