Even if you don’t give a flip about Simon & Garfunkel folk-rock classics like “The Sound of Silence” or “Bridge over Troubled Water,” or the controversy surrounding Paul Simon’s use of South African musicians for his best-known solo album Graceland during the Apartheid boycott, you know Rhymin’ Simon. He’s the guy who learned how to incorporate African music into rock from Vampire Weekend. Wait. Maybe it’s opposite.
