Nino Tempo & April Stevens were siblings who each found success in show business before they teamed up in the early 1960s, scoring a number one hit with "Deep Purple" in November 1963. Their sound was upbeat vocal pop enlivened with a light rock & roll swing, as their unfussy harmonies squared off against Tempo's production and guitar work and Stevens' breathy spoken passages. Tempo & Stevens made an effort to move with the times, hitting the Top 40 in 1966 with "All Strung Out" (an impressive simulacrum of Phil Spector's Wall of Sound) and recording the theme from the film Love Story with a light funk groove in 1972, but the playful sound of their early hits was still the foundation of their fame decades later.
