As the drummer for legendary L.A. session squad The Wrecking Crew, Hal Blaine powered a jaw-dropping number of ’60s/’70s pop and rock milestones that helped define American music. His blend of passion and precision is behind the signature “Phil Spector beat” of The Ronettes’ “Be My Baby,” the hang-ten sound of The Beach Boys’ surf-rock anthem “Fun, Fun, Fun,” the bawdy, bluesy slam of Sinatra’s “That’s Life,” and countless other immortal tunes.
