FACTBOX: Five facts about music producer Phil Spector

(Reuters) - The judge in the murder trial of music producer Phil Spector said on Tuesday that the jury was unable to reach a unanimous verdict.

Spector, 67, is accused of second-degree murder in the shooting death of actress Lana Clarkson.

Here are five facts about Spector:

* Spector created his "Wall of Sound" production style by employing large groups of musicians, sometimes using double and triple instrumentation, to create a dense sound. He once described his technique as "a Wagnerian approach to rock 'n' roll: little symphonies for the kids."

* Spector worked with some of the biggest names of the 1960s and 1970s, including the Righteous Brothers, the Ronettes, Ike and Tina Turner, the Ramones and the Beatles, as well as John Lennon and George Harrison individually.

* Stories about Spector and gunplay are legendary. According to the biography "Wall of Pain," he sometimes kept a gun on the studio recording console, fired a shot during an acrimonious recording session with Lennon and pressed a pistol barrel to Leonard Cohen's neck.

* The inscription on his father's tombstone provided the inspiration for Spector's first hit, "To Know Him Is to Love Him," recorded by his group, the Teddy Bears, in 1958. Spector's father committed suicide.

* Spector played a cocaine dealer in the hippie-era movie "Easy Rider." He also appeared on the 1960s sitcom "I Dream of Jeannie."
