For the past year, Bob has been working on an audio docu-series that traces musicians' activism for human rights through benefit concerts from the 1970s to the 1990s. That series, Concerts of Change: The Soundtrack of Human Rights, airs Tuesday, March 22 on Siriux/XM's Volume Channel (106), so in this episode, Bob and Ben mark the occasion by discussion Bob's work on the series, how studying and speaking with musicians who inspired him helped Bob reflect upon his own role as a musician, and what he learned from his conversations with those involved in Live Aid, Band Aid, and other musicians' efforts to use their talents to help improve the lives of others.

Concerts of Change: The Soundtrack of Human Rights begins on March 22 at 1 p.m. ET and will air bi-weekly on SiriusXM's Volume channel 106. Extended bonus content with longer interviews and outtakes will be available exclusively on the SiriusXM app beginning March 22.
