Walter Becker, legendary guitarist and co-founder of Rock and Roll Hall of Fame-honored band Steely Dan, has passed away at the age of 67. Becker died Sunday (Sept. 2) with the musician's official website breaking the news to the public. The cause of Becker's death is still unknown.

Becker's band Steely Dan was known for blending jazz, R&B and rock music for a signature sound in the early 1970s. Though the lineup of Steely Dan changed quite often, Becker along with co-founder Donald Fagen remained constants in the band. The group is best known for 1970's hits like "Reelin' in the Years," "Dirty Work" and "Do It Again," but have been sampled by hip-hop artists over the years, giving new meaning to their classics. Ice Cube sampled their song "Green Earrings" for his 1992 song "Don't Trust 'Em" and Kanye West sampled the band's "Kid Charlemagne" in 2007 for his own track "Champion."

With Steely Dan and #RIPWalterBecker both trending on social media, members of the hip-hop community caught on to the news and reacted online. "rip #WalterBecker possibly one of my favorite architects of the 70s "FM" smooth sound," wrote ?uestlove on Instagram along with a throwback photo of Becker. "Thank you Mr. Becker for a lifetime of great music," commented Talib Kweli on Twitter.
