The Hi-Lo's tower among the most innovative and influential close harmony quartets of the postwar era, expanding the parameters of traditional pop via sophisticated, jazz-inspired arrangements that profoundly shaped the rock & roll generation who followed in the group's wake. So named for their expansive vocal range, the Hi-Lo's formed in Hollywood in early 1953 -- bass baritone Gene Puerling and baritone Bob Strasen first teamed in the Milwaukee-based Four Shades, while baritone Bob Morse and tenor Clark Burroughs previously collaborated as members of the Encores, a short-lived ensemble led by session vocal legend Randy Van Horne. After bandleader (and future film composing icon) Jerry Fielding recommended the Hi-Lo's to the fledgling L.A. label Trend, the group cut its debut EP in April 1953, scoring a minor local hit with "Georgia." "Love Me or Leave Me," recorded in support of singer Herb Jeffries, soon followed on Olympic.
