Double Barrel Benefit (DBB), is WKNC-FM's annual fundraiser that provides for two nights of music from local North Carolina based bands. The benefit series was first organized by former General Manager Jamie Procter and held January 4–5, 2004 in Raleigh, North Carolina. The benefit changed locations for the first time in 2008, when the venue changed from Kings Barcade to The Pour House. The concert returned to the newly reopened Kings Barcade in 2011 and then returned to The Pour House in 2012. In 2014, the show split weekends and venues, holding the event at Lincoln Theatre in Raleigh and Cat's Cradle in Carrboro. The event returned to the same weekend and venue in 2017.
In 2011, each attendant to either night was given a CD of material from each artist that performed, with the exception of Inflowential, who had to cancel their appearance. The album featured new material from the acts, and the majority was recorded on the campus of North Carolina State University.
