I wasn't aware that he had died three days ago. RIP.
EDIT: I'll just leave this Topeka newspaper article (though he was originally from Chicago).

The news hit yesterday when his wife announced it.
Truly love the band Kansas, though Steinhardt only had a decade-worth of time in the band since the early-80's. He brought an element to rock music that no one else really had before, and did a damn good job doing so.
