The Trash Cats guitarist Sean Mahoney and keyboard player Matt Sjelin don’t have four paws and a tail but they do have a smooth brand of acoustic rock that purrs and meows like a happy tabby just before dinner time. The duo plays catchy, clever originals and rock covers from well-known bands like Green Day and Fun or Minneapolis experimentalists Wookiefoot. The tight harmonies and spot-on instrumentation comes from playing together for almost a decade. The band’s Facebook page features regular basement live streams.
