From Amazon:

7 years ago Neil Finn & friends first got together to perform some live shows and release the resulting live album. In December 08/January 09, Neil did it again, only this time bigger and better! He assembled a group of his friends and fellow artists in Auckland, New Zealand to record a brand new album of all new & original material. In January they also performed 3 sold out shows at the Powerstation venue in Auckland, generating much media & public interest. This time the beneficiaries of this album will be Oxfam. The cast list this time includes Neil, Sharon & Liam Finn, Bic Runga, KT Tunstall, Johnny Marr, Jeff Tweedy & Glenn Kotche (of Wilco), Ed O'Brien & Phil Selway (of Radiohead), Lisa Germano, Don McGlashan.

Amazon lists the 18th as the release date while the band's myspace page lists the 31rst
