Probably not Alembic related, but a HUGE influence to me in my musical journey. He was orchestral arranger to Jethro Tull since 1968 and became a full time member on keyboards in the mid to late 70's with the band. After his wife's passing in 2004, he transitioned and kept busy up until her passing this week. Made it to 88.  

Thanks for posting this news.  Here is the Wikipedia page.

I had no idea she did so many of the arrangements. 
Tull was a big part of my youth.
Thanks Dee.
