The concert at the WGT will be (very probably) the last concert of Cawatana (in this form). What can be expected for the future? I don’t know yet. The range is quite wide from ‘absolutely nothing’ to ‘something completely different’.
Update, to avoid misunderstandings: Cawatana is still ready to play concerts, but (probably) in different form(s) than in the past. To ask about the current situation, write an e-mail to firstname.lastname@example.org
