The death of Booker T. and the MGs bass player Donald ‘Duck’ Dunn has shaken the entire music world, with many rock greats logging on to Twitter to say how much Dunn’s music meant to them. One of those is Slash, who tweeted the message below to his more than 1.5 million followers.

Dunn passed away in his sleep Sunday morning (May 13) after playing two shows at the Blue Note nightclub in Tokyo. His work graced innumerable classic soul records, including every hit by such Stax Records legends as Otis Redding, Sam and Dave and Eddie Floyd. As a session musician, he worked with many of rock’s most famous blues-influenced stars, including Eric Clapton, Bob Dylan, Neil Young and Rod Stewart. He also appeared as himself in the 1980 film ‘The Blues Brothers,’ starring Dan Aykroyd and John Belushi.

Slash is currently on tour promoting his upcoming album, ‘Apocalyptic Love,’ which will be released May 22 on his own Dik Hayd label.
