Jon Troast : The man in the red sneakers.  Well, I look forward to the day when I can tell my kids that I once shared a stage with this guy.  He is a great guy, and an amazing singer-song writer.  Seemingly always in the middle of a coast-to-coast tour, it's a treat when he's in town.  He just moved down to Nashville, but he makes his way through the Chicagoland area from time to time.  Jon and his music are truly a breath of fresh air.  You should go give a listen to a tune or 2 on his website.

It's definitely worth your time.
