 Sinai 48 is the first reunion of the other band members since Buckingham and Nicks joined Fleetwood Mac.The band is named after Costco's brand of Kosher Polish Hotdogs, as three of the four band members are Jewish.Sinai 48, like US electronic indie pop outfit The Postal Service, did not traditionally record live performances together in the studio while creating their upcoming album; instead, they produced and arranged the album via the internet and the United States Postal Service by transferring pieces composed by McCarrell back and forth for each other to build upon, with written arrangement directions.
