Chris Porterfield is the guy you bring home to Mom. Earnest, heartfelt, and yes, a little tortured – but not irreparably so.  He’s also the front man and lead singer of the band Field Report, who played the Hi-Dive to a mellow but appreciative crowd on November 11th. It was the coldest day in my memory of Denver, so credit is due to the intrepid fans who ventured out.
