Aside from the Beatles and perhaps the Beach Boys, no mid-'60s rock group wrote melodies as gorgeous as those of the Zombies. Dominated by Colin Blunstone's breathy vocals, choral backup harmonies, and Rod Argent's shining jazz- and classical-influenced organ and piano, the band sounded utterly unique for their era. Indeed, their material -- penned by either Argent or guitarist Chris White, with unexpected shifts from major to minor keys -- was perhaps too adventurous for the singles market. To this day, they're known primarily for their three big hit singles, "She's Not There" (1964), "Tell Her No" (1965), and "Time of the Season" (1969). Most listeners remain unaware that the group maintained a remarkably high quality of work for several years.
