Every other Sunday evening (or so), a group of musicians gathers at the Barley House. As night bleeds into morning, they trade off the spotlight for short acoustic sets--nothing fancy, just a guy and a guitar and a stool, perhaps, the kind of earnest-looking scene that sends most beer-drinkers clamoring for the check. Except these are some of the best musicians in Dallas--members of Sorta and Deadman and The Shimmers--and though they're surely happy to see a large crowd gather, they're really playing for each other, trying to impress and entertain and surprise the other musicians. The set list continues to change, too, with special guests and tweaked lineups each week, meaning two shows are never the same. It's a wonderfully relaxing, feel-good way to end a week. Pull up a stool, order a beer and eavesdrop on some of the finest musical conversations around.
