Martyn Jerel Buchwald is not a rock star name- it's the name of a character from a Vonnegut book or something like that.
Grace, Jorma and Casady are all still alive. But yeah, it is kinda strange to have Kantner and Balin die within a couple years of one another. But don'e forget- Jaki and Holger from Can died within *8 months* of one another last year. That was kinda spooky.
But anyway, RIP Marty. An argument could be made that he was the main creative force behind one of my favorite albums (even if my favorite song on it was written by Slick- generally tend to favor hers over the others', actually, but Balin's stuff on "Pillow" obviously still ranks among the group's absolute best).
