When vocalist Jasmyn Burke goes into the studio to work on a song, she improvises. The lyrics come naturally, and a freshly unbalanced melody seems to follow. Mistakes are made, surprises seep through, and in that, music is born.

For Burke, and the rest of the members of the Canadian indie progressive-pop quartet, Weaves, nothing is premeditated. Including their quick rise to fame.

Burke, guitarist Morgan Waters, drummer Spencer Cole and bassist Zach Bines formed Weaves in 2013. By the following year, they had released a few singles and a critically acclaimed self-titled six-song EP. The band easily and quickly began taking over the scene.

"It may have happened fast, but it certainly didn't feel like that to us," Burke said. "It seems like we've always been working at it. We still are."

And that's what makes their sound unique, combining creative harmony peppered with pop, R&B and classic rock to create this angular melody, albeit ever-changing. (And even that is over-simplifying it.) This is the type of band you want to hear live, to see the progression play out with surprises that move both the audience and the musicians themselves.

"Start to finish, we may not know where the music will land," Burke said. "But we want to play for our audience; for all the people listening. We like the cramped venues, the smaller stages where you can see people, you can go out into the audience. You can be more of a performer and feel super connected."

But most of all, they want the music to stay relevant.

"The language of music has changed," Burke said. "How people listen to music has changed. It's more compartmentalized. So we shake things up to make it interesting for our audience - and us, too."

This controlled chaos works well for Weaves. They lurch between super-charged, booty-shaking tunes like "Buttercup" and "Motorcycle," delicate melodic tones such as "Do You See Past," classic rockers "Closer" and head bangers like the song "Take a Dip."

And while the music mostly stays true to the passing genre, each time it's played is a new experience.

"If you want the song to stay fresh, you simply change the medley," Burke said.

The Weaves are currently on tour, stopping in Savannah before their debut performance at SXSW. The band will continue on the road for more than a month in the U.S. before landing back in Ontario, where they will no doubt hunker down and continue to make music that refuses to settle nicely into a specific genre.
