We just discovered this cool little underground comic through the folks over at Ebullition. Feedback is drawn and published by Portland artist John Isaacson, who reviews local metal, punk and noise shows in comic strip form, which he collects in each issue of the half-sized black and white comic. His show review strips are short and succinct, but manage to sum up what each of these noisy, often chaotic shows was like to attend in a humorous style that reminds me a lot of Brian Walsby (of Manchild fame). We've picked up a couple of recent issues of Feedback for C-Blast, 'cuz they're worth checking out if you're into the irreverent, observational music-centric comics of Walsby and Ben Snakepit.

Issue six of Isaacson's Feedback is bumped up to thirty-two pages, with a bunch of four panel comics that reviews a bunch of Portland shows that Isaacson attended, including bands like Polvo, Lungfish front man Daniel Higgs, proggy crustcore punks Nux Vomica, one man sludge band Thrones, psychedelic sludge weirdos Wildildlife, and retro speed metallers Enforcer.
