LET THERE BE LIGHT | Next week, as summer continues to wither on the vine, a new dance-theater venture comes to Portland Stage Company. Esduardo Mariscal’s LUZ (LIGHT) looks like it could dazzle, through the 24th at 25A Forest Ave. Elsewhere, the skuzzy roots-punk band Ghost Wolves, from Austin, are a perfect pairing for the sour country-folk of Wesley Allen Hartley and the Traveling Trees at the Oak and the Ax in Biddeford. 8 pm; $8. Keep it sunny.
