Very sad news today: Beatles producer George Martin, has passed away at age 90.
Like Brian Epstein, Martin was crucial to the Beatles' early success. He also helped them grow, acting as collaborator and mentor and, most importantly, giving the group the freedom to change and experiment as their music grew ever more original and sophisticated.
The BBC, New York Times, Billboard and many other outlets have obituaries of Martin today.
We'll undoubtedly be saying and sharing much more about him here, but for now, we say a sad farewell to a great man.
