The musician had been battling Parkinson's disease since 2014. In an interview Bandwagon conducted with him last year ahead of Mr. Big's October concert in Singapore, Torpey revealed that his condition had "affected the recording of the album", stating that it "messes with your technique a little bit and your endurance and you get fatigued easily."

On how he dealt with the condition, he said, "It's a part of what I do. You just accept it and do the best you can." He further shared, "The crowds and fans have been treating me great and they're so wonderful. It really gives me a lot of inspiration to continue on."

Before forming Mr. Big, Torpey drummed for Tina Turner and Belinda Carlisle. Mr. Big released their debut album in 1989, but it was their 1991 effort Lean Into It that became their breakthrough. R.I.P., Pat Torpey.
