Many of my CDs went missing and I was really missing my blues. I had not realized Glenn had come out with so many more CDs since the last time I saw him or bought any. Never heard cardboard box, just bought it because it was there. Very happy I bought it. Some of the best old school sound I have heard in a long time.Glenn's music continues to deliver. The more he goes into his blues genre the better his music is.Where he lives in Chicago and what he sees each day is the inspiration for most of this. This is the blues experience.
