In a lengthy Facebook post, Imbolden, who replaced original Chicago drummer Danny Seraphine in 1990, explains that his decision to leave the band came “after many sleepless nights and much soul searching.”

He explains, “I realize the great honor I was given to have played drums with this incredible band for quite nearly three decades, however, at this point in my life I no longer want to commit to 9 to 10 months out of every year being on the road. This in no small way is because I have finally found and married the love of my life, Mary, and I want to share more of my life with her.”

Imbolden also points out that he isn’t retiring from playing music, and he’s “in negotiations with a major artist right now that will require much less time away from home and loved ones.”

Chicago reports that the band’s percussionist, Walfredo Reyes Jr., will take over on drums.

Meanwhile, singer/bassist Jeff Coffey, who officially replaced Jason Scheff in Chicago in October 2016, has also exited the group. In his place, Neil Donell has been welcomed as the band’s high-tenor vocalist, while Brett Simons has become the new bass player. Donell had been an occasional guest vocalist with Chicago, while Simons previously has played with Brian Wilson, Melissa Etheridge and Fiona Apple.

Regarding Imbolden, Chicago says, “We are fortunate to have known him and grateful to have shared the stage with him these many years. He has been a great friend and band mate.”
