Commuting from Providence//Boston: What commuter rails in boston run after midnight to providence?

My destination is the Paradise Rock Club in Boston, MA to see a concert that starts at 9. I know the concert probably wont be over until midnight at the earliest, and i know some trains stop running well before then. I was planning on taking the Providence Amtrak to the Boston Back Bay station. Then i would take Copley Station to Pleasant Station. The problem is getting back to providence. Is there an easier way to get from providence to the paradise rock club and back? Does anyone who commutes know rails that run after midnight?
