Chicago has added a string of new dates to its 2013 itinerary. The band kicks off its shows for the year tonight, tomorrow, and Sunday (February 15th 16th, and 17th) at Las Vegas' Tropicana Resort & Casino. As of now, the band has dates on the books through August 30th, when they play Council Bluffs, Iowa's Harrah's Ballroom.

Trumpet player and Chicago co-founder Lee Loughnane says that he always knew that music was his calling: "I knew that this is what I wanted to do, and I was gonna do it -- you know, when I was a kid, I was saying, 'I wanna do this... I don't wanna do anything else.' But I had no idea that (chuckles) it would actually come true! (laughs)" )
