He likened Brockaflower to "a big family" that manages its form and function through consensus decisions and neo-hippie directives.
There was not a hint of romance between players, he said, who lived to play together but were loathe "to get weird at the metaphoric water cooler".
The capital city band has members who hail from across New Zealand and from as far away as Hawaii (vocalist Zoe Moon Mahal) and England (trombonist Gareth Thompson-Darling). And bigger for Brockaflower is definitely better, he said.
"The size of the band has always been seen as our biggest drawcard because no matter the crowd there's always a party going down onstage. We've always got enough of us to ensure we all have the energy to have lots of fun."
The magnitude of Brockaflower also forced an extended period before the studio-bound tunes, all written ahead of recording, were polished to the satisfaction of all.
The protracted album production work also forged refinements to their live repertoire, he said, and songs cut to the album likewise morphed in the making.
"There definitely were changes. We had to adjust some things that wouldn't work as well recorded, and alternatively some stuff was better live after we changed things around.
"Even since we finished recording, there's some songs on the album which we play slightly differently now. We've added some things and taken some things out. It took so long, we did a few tours and shows in the meantime, and it's hard not to develop," Stewart said.
"This was our first studio recording and while some tracks came quicker than others, we played and workshopped and played again and were each very particular about what we liked."
