Martin (bottom left) moved away from his native Canada in the early 1960s
Canadian-born musician Dewey Martin, who played drums with 1960s band Buffalo Springfield, has died at the age of 68 in California.
Martin was a founder member of the folk rock band in 1966, which launched the careers of bandmates Neil Young and Stephen Stills.
The band released only three albums before disbanding in 1968, but had a considerable inpact on the music scene.
Young wrote of Martin: "He can feel the music, you don't have to tell him."
Young's autobiography, Shaky, tells how "You get harder, he hits harder. You pull back, he hits back."
In additional to drumming, Martin also sang background vocals on the group's biggest hit, For What It's Worth, with its famous lyric: "Stop, hey, what's that sound?"
After the band split in 1968, Martin tried to continue Buffalo Springfield with a new line-up of musicians.
Stills and Young successfully sued to prevent him from using the name without their participation.
During the 1980s Martin continued to play shows as Buffalo Springfield Revisited with the band's original bass player, Bruce Palmer.
Born Walter Milton Dewayne Midkiff, Martin took up the drums at the age of 13.
After a stint in the US army he worked his way around Nashville, playing sessions for all the country greats including Patsy Cline, Roy Orbison and The Everley Brothers.
He was inducted into the Rock and Roll Hall of Fame in 1997.
Fellow drummer Mickey Dolenz of The Monkees paid tribute to Martin.
"It's a great loss. He was a great drummer, it's a well-known fact. And he was a really nice guy."
