This is a set of about 20 CD's that I got last year. If you are a fan of teh blues, this is a spectacular recording and compilation of not only live performances at The House of Blues in Chicago but also a good number of studio recordings. There are alot of recognizable artists on the compilation. I was lucky and got it on a special for about 60 bucks. It's probably more, maybe less by now but defintly a must-have for the blues/jazz fan!
