The Barr Brothers is a Canadian folk quartet founded in Montreal, Quebec, consisting of Andrew and Brad Barr (of The Slip), Sarah Page and Andres Vial. Their first (and eponymous-titled) album was released in 2011.

Best known as founding members of the spirited and unpredictable rock trio The Slip, brothers Andrew and Brad Barr had spent most of the 90s criss-crossing North America. In the spring of 2004, the band was playing a small club in Montreal, QC when a fire broke out in the venue.

They grabbed a few guitars/drums and rushed out onto the rainy street with the rest of the concert goers. As the club's mezzanine was swallowed by flames, Andrew offered his coat to one of the waitresses from the bar.

One year later, Brad and Andrew Barr were living in Montreal. That waitress is now one of their managers. In his first apartment in the new city, Brad shared an adjoining wall with Sarah Page, a classically-trained harpist from Montreal, whose melodies would seep through the cracks of the wall and into the music Brad was writing.

From this nebulous relationship, a friendship developed and the brothers, with Sarah, began recording and performing around Montreal. Soon, their friend and multi-instrumentalist Andres Vial was brought in to lend his wide array of expertise to the outfit, playing keyboards, bass, vibes, percussion, and singing.

In 2006 they began to call themselves The Barr Brothers.
