There can't be too many siblings out there who've gone from forming a two-piece band as early teens and playing at their local county fair, to winning a Grammy for Best Hard Rock/Metal Performance 15 years later.
But that's the story of Arejay (drums) and Lzzy Hale (vocals), who formed Halestorm as classic rock-mad kids in Pennsylvania, and gathered two further band mates in the early 2000s before they signed with Atlantic Records.
Since then, they seem to have remained immune to the waxing and waning enthusiasm for rock music worldwide, and have steadily grown their fan base, touring the US, and winning that coveted 2012 Grammy - becoming the first female-fronted band to both be nominated and win in that category.
"Yeah, it blows my mind, I feel like a very lucky girl," Lzzy laughs down the line from her home in Nashville. "It was totally nuts, because it feels like that doesn't happen to bands like us. It was like something we joked about came true. But that was very much a stop-and-smell-the-roses moment for us. We all went out afterwards and sat down with a glass of champagne and had a toast, and just shared lots of stories like 'Remember when we played Fiddlesticks, and there were four people in the crowd? Can you believe we came all the way to this?' So yeah, it was a very cool moment."
Lzzy looks like the ultimate glam-rock chick in the Halestorm photos, but over the phone she's distinctly down to earth, a little goofy even, with a husky, friendly voice, and is clearly thrilled to be coming to perform in New Zealand for the first time.
