It's 7.30pm on a Monday night and Six60 are ensconced in an Auckland recording studio.
Fans of the Kiwi six-piece know they're back in the country after a full-on year touring Europe and North America and that they're working on a "top secret" project because cryptic one-liners and the not so cryptic #itunes - that's hash-tag iTunes for the social media-challenged - have been trickling through on Twitter, Facebook and Instagram all weekend.
But the cat's out of the bag now - it was confirmed on Friday that Six60 have joined the ranks of an exclusive, global group of musicians, after being invited to record an iTunes session. They follow in the footsteps of The Black Keys, Fun, Bon Iver, Alabama Shakes and Emeli Sande.
Neil Finn's Roundhead Studios is abuzz with activity. Recording is well under way and band members Matiu Walters, Chris Mac, Marlon Gerbes, Ji Fraser and Eli Paewai are getting stuck in. So it takes some gentle coaxing to get Mac and Fraser to sit down for a quick chat. But when they do, it's clear this is a significant milestone for a group that only sprang to life six years ago, after a couple of the lads threw together a flat-band while living at number 660 on Dunedin's infamous Castle St.
