Awash in controversy and loaded with revolutionary protest, Jefferson Airplane’s Volunteers stands as the last album made by the group’s classic lineup and brings insurgent closure to the peace-and-love era. The potent 1969 record confronts war, politics, greed, and environmental ruin in head-on fashion matched by few peers. Steeped in the belief people and music could transform the world, it steers the band in community-minded and county-rock directions, and features charged playing by guest luminaries such as Jerry Garcia, Stephen Stills, David Crosby, and Nicky Hopkins. Volunteers also benefits from being one of the first 16-track recordings. And now, the historic set can be heard in the fidelity the artists and producers intended.
