The former American Breed frontman passed away on Saturday (16Jan16) following a battle with pancreatic cancer.

Loizzo formed American Breed in the 1960s and they went on to enjoy hits like Bend Me, Shape Me, Step Out of Your Mind and Green Light, before breaking up in 1969.

Loizzo opened Pumpkin Studios in Chicago, Illinois in the 1970s and was responsible for engineering songs by several artists including REO Speedwagon, Styx, Slash, Survivor, and Liza Minnelli.

He was nominated for two Grammy Awards for his work with the Styx albums Cornerstone and Kilroy Was Here.

Paying tribute to Loizzo on, Styx drummer Todd Sucherman, writes, "Gary Loizzo, RIP my dear friend. This is a hard one to write as it’s one of our own... He was a man of exceptional taste, wonderful musicianship, eagle sharp ears, but most of all he was a shining example as how to conduct yourself as a man, a professional, a husband and father.

"In 20 years I never saw him lose his cool or raise his voice to anyone, and believe me, the road can be frustrating at times. He just made everyone feel good. He was a magical person and I know everyone in our organization feels they are a better human being having had the privilege to wok along his side."

"Can we please cure cancer," the drummer continues. "Enough already... I love you, and you will continue to be an inspiration and a shining example of how to live life."
