Colour it Greenpeace

John Butler Trio.

A Greenpeace concert of New Zealand and Australian artists at Auckland's St James Theatre will mark the 20th anniversary of the bombing of the Rainbow Warrior on July 10.

The lineup includes Aussie roots band the John Butler Trio, Steriogram, the D4, Rhombus, Che Fu, Don McGlashan and John Segovia, and OpShop.

Local musicians have also rallied for the occasion by recording a special version of the Muttonbirds' Anchor Me. Featuring Goldenhorse's Kirsten Morelle, Che Fu, Anika Moa, Pluto's Milan Borich, Adeaze, Hinewehi Mohi and Nesian Mystik's David Atai and Donald McNulty, the track will be released on July 4, with proceeds to Greenpeace.

It is also hoped those artists will perform at the Greenpeace gig just before 11.50pm, the time the second bomb went off.

Tickets are $40, plus booking fee. Available through Ticket Direct.
