recently came across a 2-CD set, recorded in 2006 at the University
of Rhode Island URI.
Don't see it mentioned on Mudcat, but search may not have found it.
There is a link to information about the release, but the website
mentioned for purchase is no longer active.
Is the set no longer available ???

"URI hosted musical history when the 2006 Honors Colloquium, "Songs of Social Justice: The Rhetoric of Music," explored how music has, and will always be, a constant theme in shaping the political and social experience.
Such accomplished musicians as Buffy Sainte-Marie, Tom Paxton, and the late Utah Phillips participated, sharing their thoughts and their music live Edwards Auditorium. The series was captured in a just released two-disc compilation CD, fittingly called Songs of Social Justice.
"The recordings are stunningly good, beautifully recorded, nicely edited, and capture some wonderfully unique performances. These may be the best recordings ever made of some of these artists, " said musical legend and flat-picking pioneer Dan Crary."

note: each song has an INTRO track, and a SONG track, I have
NOT shown that in this list.
