Recommendations for ballet or orchestra/symphony performances in the fall

My birthday is in September, and I was thinking MAYBE, just maybe, if there's no terrible new vaccine-resistant COVID variant at that time, I could conceivably go to the symphony or ballet for my birthday this year. Then I looked up Houston Symphony and Houston Ballet but oops, they only have performances in the spring. Does anyone know of any good companies or groups that perform in Houston in the fall? TIA
