The 19-year-old folk blues and country artist covered on acoustic guitar The Wild Hunt by the Tallest Man on Earth and Keep Your Head Up by Ben Howard, then her original song Rise and an untitled composition, before playing her four-track record with her three-piece band to great audience applause.
Her EP (extended play) includes the title song, Diamonds, the crowd-pleasing banjo-accompanied stomper Spring and her award-winning signature song Wolves & Moons.
''My thanks to everyone who came. It was amazing seeing such a big crowd and the energy was amazing as well,'' Miss Arrowsmith said on Saturday.
''I don't feel it could have gone any better. It was everything I wished for.''
The artist said she was pursuing her career in music full-time.
She next plays live on the main stage before Dave Dobbyn at the opening party of the Queenstown Winter Festival on Friday, then during the festival's Community Carnival on June 30.
