Al Green
7:30 p.m. Saturday at The Venue at Horseshoe Casino; $45-$85
Although Reverend Al Green's voice has waned a bit over the years, his last solo album, Lay It Down, proved that he still has the pipes — and charisma — to capture a listener's heart. For his set at Horseshoe Casino you can expect him to explore some of those new ventures, but rest assured, no Al Green performance is complete without a stop through some of his classic Hi Records material.

The Ruby Sunrise
7:30 p.m. through Sunday at Theater on the Lake; $17.50
In summertime, the good television is on stage. Rinne Froff's fantasia, about a female inventor and her sitcom-writing daughter, is a quick-witted story of girl genius and its casualties. The show, a remount of the Gift's immensely appealing 2009 production, plays at Theater on the Lake this weekend only. If you want to catch it, get off the couch.
