“I hope that, 55 years from now, listeners will actually feel something about our music and our lyrics," founding member Robert Lamm said in a statement. "I mean, we’re all human. We all go through some variation of the same pain and joy at some point in our lives, and there’s a commonality to that. I hope listeners in the future will actually get all those feelings while listening to our music.”

The current Chicago lineup includes three active original members: singer and keyboardist Lamm, trumpeter Loughnane and trombonist James Pankow. Other band members include Ray Herrmann on sax and flute, Wally Reyes, Jr. on drums, Neil Donell on vocals, Ramon "Ray" Yslas on percussion, Tony Obrohta on guitar, Loren Gold on keyboards and vocals, and Eric Baines on bass and vocals.
