The tanpura stuff is possibly from a commision he did for the Australian Chamber Orchestra. It's a strongly Indian influenced piece called Water.
But it hasn't been properly premiered yet, here are the upcoming performance dates:
October 26 - Melbourne, AU @ Melbourne Arts Centre
October 27 - Melbourne, AU @ Melbourne Arts Centre
October 29 - Perth, AU @ Venue TBD
November 1 - Canberra, AU @ Venue TBD
November 2 - Sydney, AU @ Sydney Opera House
So yeah, back to square one.
But you know, maybe I should go see that. That's just after my birthday, hell what if IV is playing around the same time? That would make for a great birthday.
