Stephen Stills is a renowned American singer, songwriter, and guitarist who is best known for his work with the bands Buffalo Springfield and Crosby, Stills, Nash & Young (CSNY).

Stills was born on January 3, 1945, in Dallas, Texas, and grew up in a military family. He began playing the guitar at a young age and was influenced by blues, rock, and folk music. In 1965, he co-founded the band Buffalo Springfield, which became known for its blend of folk, rock, and country music. The band's most famous songs include "For What It's Worth" and "Mr. Soul."

After Buffalo Springfield disbanded in 1968, Stills formed the supergroup Crosby, Stills, Nash & Young with David Crosby, Graham Nash, and Neil Young. The group's harmonies and political lyrics made them a popular act in the late 1960s and early 1970s. They released a number of successful albums, including "Déjà Vu" and "4 Way Street."

Stills also had a successful solo career, releasing several albums throughout the 1970s and beyond. He has collaborated with a wide range of musicians, including Jimi Hendrix, Eric Clapton, and Joni Mitchell.

Stills' musical style is known for its intricate guitar work, soulful vocals, and socially conscious lyrics. He has been inducted into the Rock and Roll Hall of Fame twice, both as a member of Buffalo Springfield and as a member of Crosby, Stills, Nash & Young.
