Prolific bassist Donald "Duck" Dunn died at the age of 70 on Sunday in Tokyo, Japan. The Booker T. & the MGs bass player was found dead in his hotel room while touring the country.

The news was confirmed via the band's guitarist, Steve Cropper; who writes, "Today I lost my best friend, the world has lost the best guy and bass player to ever live."

Born in Memphis, Tenn. in 1941, Dunn joined Booker T. & the MGs in 1964 to replace Lewie Steinberg. The band went on to become the house band for Stax Records, a relationship that found Dunn working with some of soul's biggest acts and playing on legendary hits from artists such as Sam & Dave, Otis Redding, Wilson Pickett, Isaac Hayes and Muddy Waters

Dunn made a cameo as himself in 1980s The Blues Brothers, after which he found work with a new generation of top artists, including Eric Clapton, Bob Dylan, Stevie Nicks, Tom Petty and Neil Young.

"Duck" received the lifetime achievement Grammy in 2007 and was inducted into the Rock and Roll Hall of Fame in 1992.
