The music world is mourning the death of Walter Becker, the visionary bassist and guitarist who co-founded the '70s prog rock band Steely Dan. He was 67.

"Walter Becker was my friend, my writing partner and my bandmate since we met as students at Bard College in 1967," Steely Dan co-founder Donald Fagen wrote in a statement. "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.

"He was smart as a whip, an excellent guitarist and a great songwriter. He was cynical about human nature, including his own, and hysterically funny... I intend to keep the music we created together alive as long as I can with the Steely Dan band."

Questlove, Just Blaze, Talib Kweli, and other hip hop artists took to social media to pay tribute to Becker.

".....still holds the crown baby" rip #WalterBecker possibly one of my favorite architects of the 70s "FM" smooth sound. Took it for granted growing up ---before 10 I heard his music & Fagen's voice EVERYWHERE: supermarket, waiting rooms everywhere, cabs, offices, dentist chair, sporting events even (Sixers used to RUN "Peg" during Dr J's era) actually lol first time I got sent to principles office in 2nd grade was for "saying a bad word" (Hell, was a 4 letter word growing up & I didn't know who or what a "Peg" was but I knew someone in my class was going to 🎵"Helllllllllllllllllll"🎵 The first time we played w Michael McDonald a second after "man it's an honor" came "ok how long did Walt make you stack them vocals?" Walt was my first post "hey I dig these guys I wanna get em on a session" gig shortly after our Do you Want More album came out. I was all ready for him to make me do take after take after take like I heard he was notorious for---but uh shockingly he liked our loose playing and encouraged it. (Yeah I even tried to tune my drums Steely Dan low but he was like "I want you to sound like you, not like what we were doing way back then") This is a major loss man. An artist's artist. Someone who cared for the craft of music and pushing boundaries. They got a name for the winners in the world: his name is Becker
