With his pork pie hat and golf shirt, Jeff Przech didn’t necessarily cut the stereotyped “alt-country dude” persona Thursday in the Hygienic Art Park. But over the course of eight very fine tunes, Przech spun a fine melodic and narrative web. The occasion was the first outdoor “Live Lunch Break” of the season, and Przech deeply resonated in song and conversation with regulars and newcomers alike. If you missed it, we archive all of our “Lunch Break” concerts at theday.com/livelunch.
