Hot Summer Nights w/ Kathryn Legendre (11:00), Texas String Assembly (10:00), Gus Clark (9:00) [inside]

If her step-in set at this spring’s Two Step Inn is any indication, Kathryn Legendre’s ready to launch from local honky tonks to bigger stages. Since her debut Old Soul a decade ago, the ATX songwriter has delivered the kind of hook-laden tunes and grounded lyrics that led female artists to top the Nineties country charts, with her latest singles even adding a soulful touch. The wild bluegrass of septet Texas String Assembly picks apart last year’s raucous, jamming debut LP DOGGABONE, while Seattle transplant Gus Clark brings his sweet throwback honky-tonking and blues tenor to open. —441513
