Joseph “Dusty” Hill, ZZ Top’s bassist for more than 50 years, has died, the group’s longtime rep confirmed. No cause of death was cited. He was inducted into the Rock and Roll Hall of Fame, as a member of ZZ Top, in 2004. The band’s Billy Gibbons and Frank Beard issued a statement: “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.”

Earlier this month, Gibbons and Beard played their first performances without Hill in more than 50 years, stating that the bassist had been forced to seek medical attention “to address a hip issue,” according to a statement, although his ailment was apparently more serious than they let on. While ZZ Top was best known for their synthesizer-powered 1980s hits, they were a thoroughly Texan, heavy rock-blues band at heart, spawned from the same psychedelic scene that birthed Roky Erickson and the 13th Floor Elevators but keeping things roots and rocking throughout their more than 50-year career, even as they incorporated synthesized rhythms into their sound in the 1980s.

Hill was born in Dallas in 1949 and played cello in high school, which made for an easy transition to electric bass. He, his guitarist brother Rocky and future fellow ZZ Top bandmate Frank Beard, a drummer, played in local bands such as the Warlocks, the Cellar Dwellers and American Blues, working the same Texas touring circuits as ace guitarist Billy Gibbons’ band, the Moving Sidewalks. The brothers parted company in 1968 over musical differences, and Hill and Beard moved to Houston, where they eventually united with Gibbons in ZZ Top.

Gibbons had formed the band in 1969 and recorded a one-off independent single produced by manager Bill Ham, who would remain with them for decades. The act’s original bassist introduced the guitarist to Beard; Hill would join Gibbons and Beard for a gig in Beaumont, TX, on Feb. 10, 1970. The lineup remained the same for more than five decades: They celebrated their 50th anniversary at a San Antonio concert in February 2020.

Hill’s on-screen appearances include Back to the Future Part III, Mother Goose Rock ‘n’ Rhyme, WWE Raw and Deadwood, and as himself in the 11th-season episode of King of the Hill, “Hank Gets Dusted”, in which Hank Hill is said to be Dusty’s cousin. He also made an appearance on The Drew Carey Show as himself auditioning for a spot in Drew’s band, but is rejected because of his attachment to his trademark beard which he refers to as a ‘Texas Goatee’.
