God, this is a shock. Bill King, the voice of the Oakland A's, has passed away due to complications from hip surgery. King was one of the greats. Few broadcasters can work different sports effectively -- they're just so different to call. But King was not only the A's lead radio announcer for 25 years, he was also the Golden State Warriors and Oakland Raiders play by play guy for 20 years each.
There will never, ever, be another one like him. His intellectual reach, and his stunning vocabulary, his distain for fools and love of the games he called made him unique. For anyone who cherishes the art of calling a game, I hope you heard Bill at least once.
UPDATE, 10/19/05: KNBR has a nice tribute package with lots of audio available online.
