"You hope that all the right people are in the audience; it's a big week with a lot of different people coming through town ... and all sorts of opportunities come at any time."
But more than that, it's a chance for her to return to "the music city of America", which she says is "almost like a hometown that I keep coming back to throughout my life".
Neilson first went to Nashville with her family band, travelling in their motorhome and singing "at any opportunity we could".
They later scored a contract to perform on the General Jackson showboat, which they did for a year before becoming regulars on the Nashville Cowboy Church - a radio show hosted by Johnny Cash's sister Joanne.
The cost of flying herself and her band to Nashville, as well as covering accommodation and transport, is a tall order so Neilson's putting on a show to raise funds.
She'll perform her Songs of Sinners show at Auckland's Tuning Fork on September 1, a show she's previously performed only in Christchurch.
The show pays tribute to the gospel, jazz and country artists who influenced it - "artists like Sister Rosetta Tharpe and Mavis Staples right through to Bob Dylan and Johnny Cash".
What: Tami Neilson sings Songs of Sinners, with special guests.
When: Thursday, September 1, 8pm
Where: The Tuning Fork at Vector Arena
Tickets: $40 presale (see Ticketmaster), $50 door.
