WATCH: Pre-fame Britney Spears performs three songs in closed-door 1998 Singapore showcase

It's 2016, and Britney Spears has just recently released a warmly-received new full-length album called Glory. Bolstered by a catchy comeback narrative and standout stage performances (such as her recent MTV Video Music Awards 2016 showcase), its pretty encouraging to see everyone's favourite 90s' teen idol overcome personal struggles to achieve such a remarkable career resurgence.

Nevertheless, even the most ardent Britney fans have to admit that the Princess of Pop's true height of success came during an amazing stretch between 1999 to 2001 that saw the release of her three most recognizable albums in ...Baby One More Time, Oops!... I Did It Again and Britney. She was undeniably the biggest female music superstar on the planet at that time, and it wasn't even close.

But we're about to take you to a bygone time before the phenomenon began. A full year before her debut studio LP was released, an unpolished 17-year-old Britney Spears actually came to Singapore to preview three new songs for JIVE (her label at the time) executives at the Asian Conference Presentation Singapore

Presenting unreleased and unproven forthcoming material to a group of skeptical suits must be a terrifying thing, but as you can see, Britney was a pro from the get-go.

Sure her dance moves weren't what they would come be, but her live vocals were amazing. Wearing a black spaghetti-strap dress, the unassuming teen kicks things off with her now classic song, '…Baby One More Time' before heading into another future single in her famed ballad 'Sometimes'.

Most surprisingly though, she ends the preview with 'You Got It All', a Jets cover that only made it onto certain international editions of her debut album as a bonus track. How's that for a deep cut!

It's always surreal to be watching a future icon on the cusp of breaking through, which is why you should definitely watch this vintage 12-minute performance. Superstardom would follow just a few short months after.
