I didn't know the man personally, but it seemed that everything of his that I saw, read or heard was worthwhile, and he seems to have touched a number of people profoundly in his (too) short time on the planet.
Richard was a member of the KC forum, and posted about his live performances with Jordan Rudess in early 2011. A pic from that show here:
RIP, Richard, and thanks for sharing your gifts. Notification of his passing
on the website he shared with his wife, Caroline Meyers, for those that knew him... my condolences.
