The Slip’s Brad Barr, Patrick Watson & The Wood Arms and members of Timber Timbre will share the stage this Friday, August 5. The members of the three groups will perform a single, collaborative set featuring three to five songs from each muscians’ catalog. The performance will take place just outside Montreal at Saint-Mathieu-du-Parc, QC’s Parc National de la Mauricie. Barr’s material likely be drawn from his new Barr Brothers project, which also features Slip drummer Andrew Barr. Barr describes the set as similar to a High Sierra troubadour session but with a “much bigger PA.”
