Legendary folk musician Pete Seeger passed away due to natural causes at the age of 94 yesterday. He spent his career using his talents in folk music to champion anti-war protests and environmentalist campaigns.

Seeger sang anything from political anthems to childrens tunes with either his 12 string guitar or 5 string banjo and became particularly well known for "We Shall Overcome." He was focused on the concerns of the American left, singing for the labor movement in the 1940's and 50's, civil rights marches, Vietnam War protests, and environmental causes until the end of his life.

Throughout his career he recorded more than 100 albums and worked with other key musicians in the folk world, including Woody Guthrie, Don McLean, Bob Dylan, among many others. He was an inductee in the Rock and Roll Hall of Fame in 1996. He was an incredibly influential person not only in the folk world, but in politics as well.
