No Sinner was a Canadian blues rock band from Vancouver, British Columbia, formed around singer-songwriter Colleen Rennison, whose surname inspired the band's name when spelled backwards. Originally emerging from Rennison's weekly performances at Vancouver's Guilt & Company, the lineup solidified with guitarist Eric Campbell, drummer Ian Browne, and bassist Matt Camirand. The band released its debut album, Boo Hoo Hoo, in 2012 before signing with Provogue Records, which reissued the album across North America in 2014. Following its release, No Sinner toured extensively, performing at festivals and showcase events including South by Southwest, the WXPN Non-Comm Convention, and the UK's Dot to Dot Festival. The group's blend of blues, rock, and soul earned coverage from outlets such as Classic Rock, Exclaim!, and Vice. Their second and final album, Old Habits Die Hard, was released in 2016 through Mascot Music, after which the band concluded its recording career.
