Rob Wasserman, the go-to bass player with a resume that included working with Bob Weir in Ratdog, Neil Young, Elvis Costello, Van Morrison and others has passed away after an undisclosed illness.  Shortly after posting a tweet Wednesday (6/29) calling for those who knew Rob to "...share strength of our family with him and his family", Weir followed it with another notifying people of his passing. It read, "One of the world's most beautiful friends and artists has left us. May rob's warmth and music live in your hearts as it always has in mine."
