Nineteen months from the 2016 presidential election, the onslaught of candidate demos is just beginning. There’s no anarchist representation in our political process, but if there were, it would sound like Candidate Demo, the two-man assault delivery team from Harrisonburg. Their shrieking keyboard noise platform makes no concession to mainstream taste. Contemptuous of the melodic process, they subvert rock and notions of entertainment on the appropriately titled second release, “Let Your Agony Bells Ring.” It’s a corrosive mixture of Chrome analog mechanics, primitive drum machine bombardments and shredded throat pathologies. Candidate Demo brings its combative audio confrontations to the 25 Watt on Sunday, March 1. Richard Ripper and Cosmic Inhale open with their respective ear violations. Doors open at 9 p.m. Admission is $5. 25wattrva.com.
