LOS ANGELES -- Lyle Mays, a jazz keyboardist whose work, chiefly with the Pat Metheny Group, won nearly a dozen Grammy Awards, died Monday in Los Angeles. He was 66.
Mays had a "long battle with a recurring illness," according to Pat Metheny's website.
"Lyle was one of the greatest musicians I have ever known," Metheny wrote. "Across more than 30 years, every moment we shared in music was special. From the first notes we played together, we had an immediate bond. His broad intelligence and musical wisdom informed every aspect of who he was in every way. I will miss him with all my heart."
"Lyle was a brilliant musician and person, and a genius in every sense of the word," said a statement from his niece, composer-vocalist Aubrey Johnson. "He was my dear uncle, mentor, and friend and words cannot express the depth of my grief."
Born in Wausaukee, Wisconsin, Mays' mother and father played piano and guitar and he played organ as a youngster.
He co-founded the group with guitarist Metheny in the 1970s, where he was a performer, composer and arranger. The group's endlessly innovative fusion style incorporated everything from rock and contemporary jazz to world music.
The group won numerous jazz performance Grammys, and some for best contemporary jazz album, including 2005's award for "The Way Up." But the group also scored an award in 1998 for best rock instrumental performance for "The Roots of Coincidence."
