There are two artists with the name 8th Day. The first was an American R&B group from Detroit, Michigan, active in the 1970s. The second was co-founded by brothers Shmuel and Bentzi Marcus. The group has released three studio albums that get air play on the radio in New York and Israel. Their fresh and unique sound is complimented by their catchy lyrics (mostly English with some Hebrew and Yiddish mixed in) and their spirited vocal harmonies.
