Steely Dan guitarist and co-founder Walter Becker died on Sept. 3 at the age of 67.
While his website confirmed his death, it offers no additional details.
According to fellow band mate and co-founder Donald Fagen, Becker missed playing a few shows this summer because he had been "recovering from a procedure," reports Billboard magazine.
"Walter Becker was my friend, my writing partner and my bandmate since we met as students at Bard College in 1967," Fagen wrote in a Rolling Stone tribute to his friend. "We started writing nutty little tunes on an upright piano in a small sitting room in the lobby of Ward Manor, a mouldering old mansion on the Hudson River that the college used as a dorm."
"Like a lot of kids from fractured families, he had the knack of creative mimicry, reading people’s hidden psychology and transforming what he saw into bubbly, incisive art," Fagen later continued.
"I intend to keep the music we created together alive as long as I can with the Steely Dan band," he added.
Steely Dan rose to fame in the 1970s with their platinum debut album, "Can't Buy a Thrill," reports Us Weekly. The group split before reuniting again in 2000; that following year, they were inducted into the Rock and Roll Hall of Fame.
Becker's daughter, Sayan, also paid tribute to Becker in a piece on her father's website.
"Thanks dad for your love for music, your fatherly advice and devotion, your knowledge about the world and your blindingly sharp sense of humor ... for all that, and more," she wrote. "We had one hell of a ride. You are my world, my soulmate, my father, that I love so much. It's true your love is shining from the next galaxy. I could see it now; you got a whole galaxy of guitars to look at. Rock on dad, rock on until your heart is content."
Meanwhile, fans worldwide also mourn the loss of the musician.
"Walter Becker was a master of musical understatement," reads a headline penned by NPR writer Tom Moon.
"What Becker added to Steely Dan was an elusive strain of magic -- the terse little melodic thing that turned out to be exactly what the music needed," he added.
"Becker knew that bleakness -- and made a lifetime's worth of unforgettable music out of it," chimed in Rolling Stone writer Rob Sheffield. "He always knew how to make loserdom sound mythic. Rest in peace, Walter Becker -- we know you're smoking, wherever you are."
