Joe Zawinul, the jazz keyboardist who soared to fame as one of the creators of jazz-rock fusion with the band Weather Report, died yesterday in a hospital in Vienna, Austria. He was 75 and had been suffering from skin cancer. Zawinul won acclaim for his keyboard work on chart-topping Miles Davis albums such as “In A Silent Way” and “Bitches Brew,” and was a leading force behind the so-called “Electric Jazz” movement.

In 1970, Zawinul and saxophonist Wayne Shorter founded Weather Report and produced a series of albums including “Heavy Weather,” “Black Market,” “I Sing the Body Electric,” and the Grammy-winning live recording “8:30.” He is credited with bringing the electric piano and synthesizer into the jazz mainstream, but was frustrated by the lack of respect for electric keyboards and new technology among jazz purists.

“There is no difference between a Stradivarius or a beautiful synthesizer sound,” Zawinul told Jazziz magazine earlier this year. “People make a big mistake in putting down electronic music. Yes, it’s been misused and abused, but that’s true of every music.

Born in 1932, Zawinul grew up in a working-class family during World War II in the Austrian capital. He played accordion on the streets to make money and received classical piano training as a child prodigy at the Vienna Conservatory. He grew interested in American jazz, playing in a dance band that included the future Austrian President Thomas Klestil and making a name for himself on the local jazz scene in bands led by saxophonist Hans Koller and others.

“One thing about Viennese musicians, they can really groove, more than even the German bands can,” Zawinul said in a 2007 Downbeat magazine interview.

In 1959, Zawinul emigrated to the United States on a scholarship to study at the Berklee School of Music in Boston, but left to join Maynard Fergusion’s big band. He next landed a gig with Dinah Washington; his funky piano can be heard on her 1959 hit “What a Diff’rence a Day Made.”

Zawinul rose to international fame after joining alto saxophonist Cannonball Adderley’s band in 1961. During his nine-year stint with the band, he composed such tunes as “Walk Tall,” “Country Preacher,” and most notably the gospel-influenced, soul-jazz anthem “Mercy, Mercy, Mercy,” his first hit recording on electric piano, which climbed the pop charts and won a Grammy for Adderley.

In the late ‘60s, Zawinul recorded with Davis’ studio band, His tune “In a Silent Way” served as the title track for the trumpeter’s first foray into the electric arena. Zawinul’s composition “Pharoah’s Dance” was featured on Davis’ groundbreaking 1970 jazz-rock fusion album “Bitches Brew,” which won Davis a 1970 Grammy for best jazz performance, large group or soloist with large group.

Weather Report enjoyed its biggest commercial success with the 1977 album “Heavy Weather” which featured Zawinul’s tune “Birdland,” which became one of the most recognizable jazz hits of the 1970s after it was also recorded by Maynard Ferguson and the vocal group Manhattan Transfer. After Weather Report broke up in 1986, Zawinul went on to form The Zawinul Syndicate, which brought together a global village of musicians who recorded such albums at the Grammy-nominated “My People” (1996) and “World Tour” (1998).
