B.B. King, a titan of American music who died Thursday at 89 years old, lived for so long, did so much, and was so deeply woven into our cultural fabric that it was easy to take him for granted. “The King of the Blues,” he was called, although too often in the offhanded and unthinking tone in which people call Budweiser the King of Beers. King was a singer and guitar player of unfathomable depth and dimension, and his music was a watershed: In the middle part of the 20^th century, no performer so effortlessly melded country blues to the more urban, “modern” sounds of post–World War II rhythm and blues than King: not Muddy Waters, not Howlin’ Wolf, not the still-missed Bobby “Blue” Bland. Already on his first major hit, 1951’s “3 O’Clock Blues,” King exemplified this fusion in spades: the urbane and jazz-inflected guitar playing, the lush and billowing horns, the vocal performance that seems to channel Lonnie Johnson and Blind Lemon Jefferson out of one lung, Jimmy Rushing and Frank Sinatra out of the other.
