Banks has lost count of the shows she's played since her big break but admits she lacks experience as a punter. She'd only ever been to one festival before she played at any. That was Coachella.
"I didn't go to many gigs growing up. I mean I didn't start playing gigs until a year and a half ago. Music for me, my whole life, has been this private thing. It was like this individual thing that I enjoyed alone. And I wrote alone."
There is little alone time in a travelling festival such as Laneway. Banks can't wait.
"It sounds like the most fun you can have. Kind of like a travelling summer camp where you get to play music," she laughs.
As well as planning to wow the crowds, Banks also plans to make up for all those years of missed live gigs by catching as many of her fellow acts as possible - something she now makes a point of doing.
"It's funny, because when you're touring so much you live in your own little world. Seeing a gig reminds you of how amazing and fun it is.
"To be in an audience watching, it feels so big and it feels so special. I think it's one of the most inspiring things in the world - to see other artists doing their thing and being themselves in front of all these people."
St Jerome's Laneway Festivals is tomorrow at Silo Park in Auckland.
