This self-described “rock and roll band with horns” was inducted into the Rock and Roll Hall of Fame in 2016. Now celebrating another milestone — the 50th anniversary of their groundbreaking album "Chicago II" — the band returns to Grainger Studio in the city that inspired its name to play songs from their celebrated album, including “Make Me Smile,” “25 or 6 to 4,” and “Colour My World.”

"Soundstage" brings together these two wildly talented ensembles for the very first time.
