Remember back at the turn of the century when pop-punk held the Earth in terrified thrall of Dickies shorts, studded belts, checkered Chuck Taylors, and mind-numbingly banal, nursery-rhyme choruses delivered in double time by whiny white kids with no rhythm? And remember how worthier practitioners of the rapidly deteriorating genre, such as Gob, quietly and inconspicuously made themselves very, very scarce when that happened? Yeah, well, now that the coast is clear, the local bruisers are back with 2007’s harder-edged Muertos Vivos, and the sins of the past behind them. Whether guitarist Tom Thacker can be forgiven for his glum appearance with Sum 41 last October at the PNE Forum is another thing entirely. That’s something you’ll have to decide when Gob descends on the Commodore Ballroom on Tuesday (May 6), with Winnipeg’s Sick City.
