Billy Corgan is best known as the frontman of the Smashing Pumpkins (and for his cracking cameo in The Simpsons, let's be honest). However, in recent years his focus has been wrestling production and talent development. In 2011, he co-founded Resistance Pro Wrestling, which produces monthly events in Chicago. He left the company in 2014 to take a job as a senior producer for Total Nonstop Action Wrestling, where he still works.
