Madonna is arguably the most popular female pop singer in American musical history. Although she began her career in the late 1970s as a dancer and as drummer for new wave group the Breakfast Club, Madonna has touched upon many different styles throughout her trend-setting career, and has acted in numerous movies as well. Although her image has shifted to include looks as disparate as raunchy temptress and New Age mother, the Material Girl has always maintained a fierce business sense and a remarkable knack for controversy. Few other artists--male or female--have had the phenomenal mass adulation or the staying power of this pop culture icon.
