Music Producer Phil Spector dead at 81 from COVID-19
Phil Spector, the music producer responsible for some of the biggest hits in music and the architect of The Wall of Sound has died.

According to various sources he died from COVID-related complications, after being transferred from his prison cell to a hospital. He was diagnosed 4 weeks ago and went to the hospital but recovered well enough to return to prison, where he was serving a 19-to-life sentence for the murder of Lana Clarkson.

Our sources say he relapsed, had trouble breathing and was rushed back to the hospital, where he died Saturday.

Spector began his career early ... when he was still in high school, he produced his first big hit, "To Know Him is To Love Him," by the Teddy Bears.

Spector`s "Wall of Sound" was a technique he discovered in a tunnel near Hollywood Blvd. The sound created a roaring effect, which Spector called the "Wagnerian approach to rock `n` roll" -- it involved overdubbing scores of musicians in an orchestral style to make a fuller sound.

The technique was mimicked by the Beach Boys and Bruce Springsteen.

He was inducted into the Rock and Roll Hall of Fame in 1989.

Spector ended up in prison for the second-degree murder of Clarkson, an actress he`d met in 2003 while she was working at the House of Blues in WeHo. They went back to his mansion, and he shot her ... although he`d claimed it was an accidental suicide.

His first trial, in 2007, was declared a mistrial, due to a hung jury, but he was convicted in a 2009 retrial.
