The band announced Hill’s death on their Facebook page earlier today:
“We are saddened by the news today that our Compadre, Dusty Hill, has passed away in his sleep at home in Houston, TX. We, along with legions of ZZ Top fans around the world, will miss your steadfast presence, your good nature and enduring commitment to providing that monumental bottom to the ‘Top’. We will forever be connected to that “Blues Shuffle in C.”
You will be missed greatly, amigo.
Frank & Billy
Hill joined ZZ Top in 1970 and remained with the band through his death.
