The physical and psychic wounds inflicted by Hurricane Harvey are still raw, and will be for a while. What our ailing community needs almost as much as physical supplies is spiritual relief, a chance to come together and lift each other up, maybe sing a few songs along the way. So let’s hope this doesn’t get canceled. If Canned Acoustica organizer Mark C. Austin, who did as much to help out his fellow Houstonians during the storm as anyone, has his way, it won’t be. Founded in 2010 as a modern twist on the old-fashioned hootenanny, Canned Acoustica packed the house three years straight, channeling all monies to the Houston Food Bank and other charities. Now rebooted monthly through November, the lineup now as then features an eclectic cluster of Houston’s most vibrant acts — this time, it’s OG vatos rudos Los Skarnales, cumbia king Gio Chamba, bristling femcee Genesis Blu, slinky glam-pop auteur –Us, and singer-songwriter Romina Von Mohr — out to prove that turning down the amps doesn’t mean turning down the energy. Houston needs a show like this right now.
