Houston’s skyline isn’t the only thing that keeps jutting up and up into the stars. World-class musicians, world premiere plays, high-flying productions and high-minded lectures have all lifted Houston’s arts offerings into the stratosphere of late. What’s wrong with that, you ask? It’s all a bit much to take in, a smorgasbord too vast for all but the most gluttonous arts maven. Hence, this year’s guide, a cruelly reductive, overly selective and by definition arbitrary companion to the fall arts season.  Are there 40 other hot tickets that might have made my list? Of course there are. Do I expect to be skewered for leaving them off? Of course I do. But know this: every minute you spend here quibbling with me is one less minute you’ll have to snag the tickets below, so argue at your peril.
