This is the beginning of what will be a series in this blog of what can only be described as Great Performances. The criteria for inclusion in this series is simply an act captured live proving why they are so highly regarded. First up is a team-up of two legendary horn bands, Earth Wind And Fire and Chicago. Two distinctively different styles blending seamlessly together and appearing to be having a lot of fun in the process. The two performances to follow, one an Earth Wind And Fire song, the other a Chicago song, are from a 2004 performance at The Greek Theater in Los Angeles. I hope you enjoy them as much as I do.
