Dag Juhlin, former (?) member of the Slugs and Poi Dog Pondering, current solo artist and member of the Goldstars, teamed up Sunday night with Jason Narducy, formerly of Verbow, more recently a touring musician with Bob Mould and Robert Pollard. The two talented singer/guitarists played almost entirely covers of classic rock songs during an almost entirely unpublicized gig at Simon’s Tap in Andersonville. It was a low-key event, but still pretty fun. Juhlin’s as much of a card as ever, and it was nice to hear them weave together well-known tunes with identical chord progressions.
