The seven-song '29' is the result of her new songwriting partnership with Shane McAnally and Josh Osborne.
Notable songwriters Lucie Silvas, Erin Enderlin, Shane McAnally, and Josh Osborne are among those taking part.
'We approached it as though we were making our last record ever,' say the duo of the album.
The full-length show at the Brooklyn Bowl in Las Vegas will have a series of surprise guests.
The single juxtaposes Hunt's modern, hip-hop-influenced sound with Webb Pierce's 1953 country staple 'There Stands The Glass.'
Hunt wrote the reflective song, which opens on acoustic guitar and vocal, with Paul DiGiovanni, Josh Osborne and Emily Weisband.
The top 20 debut of the new release matches the first-week performance of Hunt's last single, 2018's 'Downtown's Dead.'
'Let It Roll' is due for release on 23 August as the follow-up to their successful 2017 debut set 'On The Rocks.'
