Ocasek, who sang, played guitar and wrote most of the band’s songs, and Benjamin Orr, who played bass and also sang, were ex-hippie buddies who formed The Cars in Boston in 1976. They were a decade older than many of their modern-rock compatriots but became one of the most essential American bands of the late 1970s and 1980s with their fusion of new wave, 1960s pop and 1970s glam.
