Founding Member of Legendary '70s Rock Band Dead at 83
The progressive rock world is mourning the loss of one of its pioneering musicians.
Dave Greenslade, the keyboardist, composer and founding member of Greenslade, has died at the age of 83. The news was announced by his daughter, Kate, in a statement shared on the band's official Facebook page.
"We are deeply saddened to share that Dave Greenslade, keyboard player, songwriter and composer, has died at the age of 83," the family wrote. "Dave was known and loved for his work with Colosseum, his own band Greenslade, and a lifetime of music that also included solo albums and television composition. He was a remarkable musician, a loving partner, father and a great friend to many."
Born in Woking, Surrey, England, in 1943, Greenslade developed a love for music at an early age. After a brief stint with Geno Washington & the Ram Jam Band, he teamed up with drummer Jon Hiseman and bassist Tony Reeves to co-found the influential jazz-rock outfit Colosseum in 1968. The band became one of the earliest groups to blend jazz improvisation with progressive rock, releasing acclaimed albums including Valentyne Suite, now considered a landmark of the genre.
"We had no idea what we were going to play so we created the music from day one," Greenslade said in a 2023 interview. "Another steep learning curve. My first shot at real composing."
In 1972, Greenslade left Colosseum to form the band that bore his name. Unusual for the era, Greenslade featured two keyboardists and no guitarist, helping the group stand out in the crowded progressive rock scene. The band released four studio albums during the 1970s, including Spyglass Guest, which became its highest-charting release in the U.K.
"I'm lucky to have had a chance to form a band with those guys," Greenslade told Prog magazine of his Greensalde bandmates in 2018. "We made a great combination. And it was a most unusual band at the time – no guitar and two keyboard players."
Beyond his work in progressive rock, Greenslade composed music for television, released several solo albums and reunited with Colosseum when the band reformed in 1994. He remained an active musician well into his later years, releasing his final solo album, Routes/Roots, in 2011 and later forming the duo G&T with guitarist David Thomas.
Although he never achieved the mainstream fame of some of his contemporaries, Dave Greenslade's adventurous keyboard playing and innovative compositions helped define the early progressive rock movement. More than half a century after helping shape the genre, his influence continues to be heard in generations of musicians who followed in his footsteps.
