Robby Steinhardt, who famously spearheaded the progressive rock band Kansas, has died. He was 71.

Through a heartfelt Facebook post, Robby's wife, Cindy Steinhardt, delivered the saddening news to the fans of the late musician.

She shared a photo of Robby playing his violin alongside a lengthy caption to honor him and his fruitful life.

"It is with an extremely heavy broken heart that I have to announce to the world, we have lost one of the most incredible people of our time.... Robby Steinhardt has passed away," she said.

The Monday update also revealed that Robby passed away at a hospital in Tampa, Florida. His passing was truly unexpected, especially since he just recorded his first solo album despite his health issues.

Robby Steinhardt's Cause of Death

Cindy detailed that the violinist's final journey began on May 13. During that time, they admitted Robby to a hospital due to acute pancreatitis. After his admission, he suffered from acute septic shock and was put on life support.

Fortunately, he beat the life-and-death situation and started to recover little by little. Sixty-five days later, the singer was supposed to be discharged from the health facility. His doctors reportedly advised him to undergo rehabilitation following his hospital confinement.

However, a fever suddenly affected his health condition and sparked another septic shock.

The wife then shared the heartbreaking last moment with him - after six minutes, he died in her arms.

"I've always tried to share our lives with you but I ask you to please respect this heavy time of grief. I encourage you to share your stories and pictures of Robby on his page. My only regret is that I can't share them with him to show him how much he is loved," she went on.
