Michelle Treacy, the Ottawa teen who took the music world by surprise two years ago with an impromptu concert duet with Lady Gaga, has just released her first major label single.

Armageddon was produced by fellow Canadian wunderkinds Todd Clark and Steve Kozmeniuk. Each of them having worked with big-time performers such as Phillip Phillips and Kendrick Lamar before working with Treacy.

"I can't put into words how incredible it feels to work so hard and finally have your childhood dreams come true," says Treacy, who turns 20 on July 17.

For Treacy, the two years since Lady Gaga plucked her from a Montreal concert crowd have been filled with travel, both physical and metaphysical.

Seeing musical capitals such as Nashville with family and friends have been a highlight. But the voyage that has seen her discover her songwriting voice was also important.

"I've realised I'm very good at telling personal stories and making them connect to other people's stories … I wasn't that good at it before," says Treacy, who discovered honesty is the path to pop gold.

Entering a writing partnership with the likes of Clark and Kozmeniuk, she says, you check your inhibitions at the studio door.

"(You say) 'OK, this is my one chance to be very vulnerable and just tell them exactly what's going on.' And they really like that ... It all comes from stories. You just have to walk into the studio and just give it."

Another highlight of the journey thus far?

"Just the reaction of seeing how much my words touched my family, my mother especially."

Upon recording one of the songs, Liar Liar, for her upcoming rookie release, she popped a set of headphones on her mom for reaction.

"She said 'Thank you for saying the words I could never say.' And she just cried."

Treacy has some decisions to make as she prepares for her debut Sony Music Entertainment Canada album release. Who else to work with to get the project finished, which musicians to hire for concerts, but also, where to live.

"We move in September … We're not sure do we move back to Ottawa?"

She says Ottawa will always be home but the pull to stay in Toronto where she's been recording, has to be strong.

One thing she does know: the band she assembles for her first tour will be homegrown. And she's off to a good start looking to Ottawa musical prodigy Lucas Haneman who's handling guitar duties.
