MADONNA
After a star reaches a certain point, it's easy to forget what they became famous for and concentrate solely on their persona. Madonna is such a star. Madonna rocketed to stardom so quickly in 1984 that it obscured most of her musical virtues. Appreciating her music became even more difficult as the decade wore on, as discussing her lifestyle became more common than discussing her music. However, one of Madonna's greatest achievements is how she manipulated the media and the public with her music, her videos, her publicity, and her sexuality. Arguably, Madonna was the first female pop star to have complete control of her music and image.ELTON JOHN
In terms of sales and lasting popularity, Elton John was the biggest pop superstar of the early '70s. Initially marketed as a singer/songwriter, John soon revealed he could craft Beatlesque pop and pound out rockers with equal aplomb. He could dip into soul, disco, and country, as well as classic pop balladry and even progressive rock. His versatility, combined with his effortless melodic skills, dynamic charisma, and flamboyant stage shows, made him the most popular recording artist of the '70s. Unlike many pop stars, John was able to sustain his popularity, charting a Top 40 single every single year from 1970 to 1996. During that time, he had temporary slumps in creativity and sales, as he fell out of favor with critics, had fights with his lyricist Bernie Taupin, and battled various addictions and public scandals. But through it all, John remained a remarkably popular artist and many of his songs -- including "Your Song," "Rocket Man," "Goodbye Yellow Brick Road," and "Don't Let the Sun Go Down on Me" -- became contemporary pop standards.THE BEACH BOYS
Beginning their career as the most popular surf band in the nation, the Beach Boys finally emerged by 1966 as America's pre-eminent pop group, the only act able to challenge (for a brief time) the overarching success of the Beatles with both mainstream listeners and the critical community. From their 1961 debut with the regional hit "Surfin," the three Wilson brothers -- Brian, Dennis, and Carl -- plus cousin Mike Love and friend Al Jardine constructed the most intricate, gorgeous harmonies ever heard from a pop band. With Brian's studio proficiency growing by leaps and bounds during the mid-'60s, the Beach Boys also proved to be one of the best-produced groups of the '60s, exemplified by their 1966 peak with the Pet Sounds LP and the number one single "Good Vibrations." Though Brian's escalating drug use and obsessive desire to trump the Beatles (by recording the perfect LP statement) eventually led to a nervous breakdown after he heard Sgt. Pepper's Lonely Hearts Club Band, the group soldiered on long into the 1970s and '80s, with Brian only an inconsistent participant. The band's post-1966 material is often maligned (if it's recognized at all), but the truth is the Beach Boys continued to make great music well into the '70s. Displayed best on 1970's Sunflower, each member revealed individual talents never fully developed during the mid-'60s -- Carl became a solid, distinctive producer and Brian's replacement as nominal bandleader, Mike continued to provide a visual focus as the frontman for live shows, and Dennis developed his own notable songwriting talents. Though legal wranglings and marginal oldies tours during the '90s often obscured what made the Beach Boys great, the band's unerring ability to surf the waves of commercial success and artistic development during the '60s made them America's first, best rock band.
