In 2001, Crowded House and Split Enz frontman Neil Finn invited a few of his musical friends down to his homeland of New Zealand to form a temporary supergroup under the moniker of 7 Worlds Collide and put on a series of concerts for charity.
The all-star players included Pearl Jam's Eddie Vedder, Johnny Marr of The Smiths and Modest Mouse, Radiohead's Phil Selway and Ed O'Brien, Neil's brother Tim Finn, also an alumnus of Crowded House and Split Enz, and Lisa Germano.
It was such as success that Finn did it again in 2009, inviting members of Wilco into the fold that included Jeff Tweedy, Glenn Kotche, John Stirratt and Pat Sansone, plus Neil's son Liam, Soul Coughing's Sebastian Steinberg and singer-songwriter KT Tunstall.
They would perform three concerts to benefit Oxfam, an association working to end poverty and injustice in 90 countries.
This time, the total of 20 musicians would also have 20 days to write and record a studio album, also benefiting the charity.
The process is beautifully chronicled in director Simon Mark-Brown's “The Sun Came Out,” a supremely entertaining, often funny and sometimes poignant behind-the-scenes documentary on the making of the album “7 Worlds Collide.”
The musicians and their families are seen converging on Finn's Auckland, New Zealand studio during the 2008 Christmas holidays, 40-plus men, women and children occupying 15 rented houses — when there was time for sleep — and hanging together during working and playing hours like a hippie-era commune.
