Herbert and Harold Kalin, twin brother harmony singers, sang like a pop-focused version of the Everly Brothers, and they charted a few catchy records in 1958, including one Top Five hit. They represent one of the better acts to find a compromise between rock & roll and pop music, even if they weren't the Everlys by a long shot.
