Jackson Browne with Sangre Machehual Backstage Pass, 1987 - 1990

A cloth concert backstage pass for a Jackson Browne acoustic performance featuring special guests Sangre Machehual. Salvadoran-born musician Osmin Aparicio became part of Los Angeles' Sangre Machehual (Blood of the Poor/Oppressed)— founded in 1978 by Hugo Pedroza (Mexican) and rooted in the Chicano Movement music— when the influence of Latin America's Nueva Cancion (protest music) and the Salvadoran solidarity movement in the U.S. pulled the band in a new direction.
