I was there! My friend and I were in Chicago for Riotfest, heard Billy was doing this a couple days in row. Being huge fans, and this day also happening to be my friend's birthday, we of course HAD to go! It was an incredibly comfortable and intimate performance, there was only about 20 people there, he also did a few requests before the stream (Soothe, Ugly, Wound, and bit of my request, With Every Light!!) It was pure magic, and so lovely talking with him for a little while :)
