Mike Boguski is Blue Rodeo’s keyboardist, a position he’s held since 2008. But like others in the group, his musical ambition extends beyond furthering the legacy of Canada’s beloved roots rock institution. Boguski’s new solo album, Blues for the Penitent, is perhaps the purest display of his talent to date, showcasing him alone at the piano on 12 instrumental pieces, which, taken as a whole, tell a powerful, emotional story.
