An American rock musician.
Known as the drummer for the music group The Knack.
He was nominated for two Grammy Awards as a stage performer, producer, and recording artist.
Gary was diagnosed with hyperactive disorder and ADD. At age 5 his parents put him on a pharmaceutical regimen of Ritalin and other drugs in a vain attempt to control his behavior.
At about that same time he was removed from public schoool and enrolled at Ridgewood Military Academy near the family home in Woodland Hills, California, where his ill-advised parents believed that military discipline would cure his hyperactivity and "inappropriate behaviors."
It has been written that Gary's parents "allowed him" to set up the drum kit that his cousin had offered him after getting bored with it. This is absolutely untrue.
At about age 15 Gary finally fled from the covert torturous physical, psychological and mental abuse as well as the daily beatings he received in the violent home of his abusive
manic-depressive mother and his angry rage-filled father.
He went to live in nearby Topanga Canyon with a family named Lathers, whose father worked at Juvenile Hall and was known to help children who were in difficult, violent or abusive situations.
In the 60's and early 70's he played and toured with bluesman Albert Collins. By the time he was twenty-four he was touring and recording with former Cream bassist Jack Bruce and guitarist Mick Taylor, who had just left the Rolling Stones.
In 1978 he found himself in a band with singer Doug Fieger, guitarist Berton Averre, and bassist Prescott Niles. Fieger and Averre brought in a tune they'd written about Sharona Alperin, a teenage girl Fieger was obsessed with. Despite his initial reservations about the song, Gary came up with a beat to match "My Sharona"'s stuttering style.
The Knack's debut album "Get the Knack" sold 6 million copies. Unfortunately, Gary did not substantially benefit financially from this, as the publishing rights never included him.
After the breakup of The Knack in the early 1980s, Gary became an in-demand drummer for studio work and live performance with some of the premier musicians of the era including Bob Dylan, George Harrison, Stephen Stills, Rod Stewart, etc.
He died at the age of 55 at the Tarzana Regional Medical Center in Tarzana, California of Non-Hodgkin lymphoma.
