"My mum had been whangai-ed from Masterton to Hawkes Bay and she reconnected with that part of our family ages ago.
"For me that connection was made only about two years ago.
"So Masterton is kind of hometown for me I guess -- it's where my roots are."
Gerbes said fan loyalty had been humbling after the release of their second self-titled studio album, which went gold within weeks of its release in February.
The second album was self-titled, like their 2011 debut album that sold platinum, to avoid the risk of listener preconceptions, he said.
Each track was written and recorded over a two-year incubation "without any pressure or expectation" burdening the band.
"It took two years to finish the second album. We've heard about guys that buckle under the pressure and put something out they're only half happy with.
"It's that second album syndrome.
"It just has to be done when you're ready, not really when the fans expect.
"You just never know when you'll be totally happy with it."
