Calliope's Sisters

Modernizing the harmony vocal pop of '30s and '40s groups like the Andrews Sisters, London's Puppini Sisters took the name of Marcella Puppini, who founded the act after being inspired by the music in the film The Triplets of Belleville. Puppini, a native of Bologna, Italy, moved to London in 1990 to study fashion and quickly became immersed in the city's music scene. Though she had a career at Vivienne Westwood's design studio, she left to focus on music, and in 2003 earned a music degree at Trinity College of Music. Jazz was her passion, and Puppini spent time as the musical director and orchestra conductor for the Whoopee Club, as well as leading her own quartet.

The Andrews Sisters were an American close harmony singing group of the swing and boogie-woogie eras. The group consisted of three sisters: contralto LaVerne Sophia, soprano Maxene Anglyn, and mezzo-soprano Patricia Marie "Patty". The sisters have sold an estimated 90 million records. Their 1941 hit "Boogie Woogie Bugle Boy" can be considered an early example of rhythm and blues or jump blues. Other songs closely associated with the Andrews Sisters include their first major hit, "Bei Mir Bist Du Schön (Means That You're Grand)" (1937), "Beer Barrel Polka (Roll Out the Barrel)" (1939), "Beat Me Daddy, Eight to the Bar" (1940), "Don't Sit Under the Apple Tree (With Anyone Else but Me)" (1942), and "Rum and Coca Cola" (1945), which helped introduce American audiences to calypso.

The Pointer Sisters are an American R&B singing group from Oakland, California that achieved mainstream success during the 1970s and 1980s.
