Only 11 total schools are selected to perform on the main stage at the festival, which will take place in Bloomington, Indiana in June. The students will perform Theory of Relativity, which they brought to the Urbana High School stage back in November. 

You can read more about the festival in this Playbill article. Also it's kind of awesome that Urbana High School is mentioned in Playbill
