Close harmony groups, such as the Four Freshmen and Four Aces, were quite viable commercially, before the advent of rock and roll made so many of them redundant. Such was the case with the Four Aces, who had over thirty top forty hits before 1958. Many of the songs on this "Greatest Hits" CD were from these hit singles, and include such classic compositions as "Should I" "Perfidia" and "Melody Of Love, " which had been popularized decades earlier. Showy orchestrations compliment the confident lead of Al Alberts and the harmonies of his emphatic cohorts, who had evolved into a tight and effective unit.
