Pearls Before Swine was an American psychedelic folk band formed by Tom Rapp in 1965 in Melbourne, Florida, United States. The group signed to ESP Disk and recorded One Nation Underground, a fairly successful release that was followed by the anti-war Balaklava (1968). In the next few years, Rapp often referred onstage, not quite seriously, to the group as "the house band for the SDS" (Students for a Democratic Society). They continued to release albums and to tour until the 1970s, but Rapp retired in 1973 and became a lawyer, practising in Florida. Tom Rapp died in 2018.
