The Motown Museum in Detroit, Mich., welcomed alumni of the famed recording label, along with members and friends, for a cocktail party celebrating the publication of Motown: The Sound of Young America (Thames & Hudson), a coffee-table volume that's both a visual archive and an insider history of Motown Records. Members of Martha and the Vandellas and the Four Tops, among others, joined author Adam White to launch the book in the U.S. Pictured: Martha Reeves (third from left) and Adam White (second from right) with the Vandellas.
