From the wiki: “The recording sounds so simple, and it is: four voices and a piano. It first aired on the radio before the records were even pressed, and the immediate and massive reaction it received forced the group to release the recording “as-is” without the additional embellishment and orchestration that had been originally planned. ‘Earth Angel’ became one of the blueprints for Doo-wop; the second such recording to hit the Top 10 (after The Chords’ ‘Sh-Boom’). The Penguins were four high school students from Fremont High in Los Angeles, and they recorded ‘Earth Angel’ in a garage and released it on a small black-owned label called Dootone Records. The recording became the first independent label release to appear on Billboard’s national pop charts.
