The beginning of 1982 marked the start of the most successful era of TOTO’s career. After an extensive schedule in the studio,
TOTO released the iconic TOTO IV. The record immediately exploded onto the charts,
producing the smash hits => "Africa" and
=> "Rosanna" and rocketing the band to instant international stardom.
TOTO IV hit platinum and yielded 5 singles.

In 1983, while TOTO IV continued to sell millions of copies worldwide, TOTO reaped the benefits of their hard work
and commercial success at the => Grammy Awards, winning six different categories,
including the coveted Album of the Year for TOTO IV and Record of the Year for "Rosanna." The record also won awards for Producer of the Year
and Best Engineered Recording, while "Rosanna" also earned Best Instrumental Arrangement Accompanying Vocals and Best Vocal Arrangement.
In addition, Steve Lukather won for Best Rhythm & Blues Song – "Turn Your Love Around" – which he co-wrote with
=> Jay Graydon and Bill Champlin.
Just prior to the TOTO IV world tour, Mike Porcaro replaced David Hungate, who had just become a father and felt his responsibilities to his family prevented him from participating in the immense world tour that followed IV’s release. Like his brothers, Mike was an accomplished session musician, and, having played with the band members in high school, Mike was a perfect replacement for Hungate. Thus the band’s first-class playing and fun-loving dynamic continued despite the personnel change.
Despite the world-wide commercial success of TOTO IV, the members of the band continued their session work, collaborating with Quincy Jones and Michael Jackson on the international hit Thriller and other artists such as => Don Henley, Van Halen, Steely Dan<, Boz Scaggs, Paul McCartney, Chicago, and Eric Clapton. During the time immediately following the TOTO IV Tour, David Paich brought in the entire band to work together on a movie score for David Lynch’s Dune, based on the best-selling science fiction novel that has since become a cult phenomenon.
During pre-production of Toto’s fifth record, Bobby Kimball left the band and was replaced by => Le Roux’s Fergie Frederiksen. In the summer of ’84, TOTO recorded the boxing theme for the 1984 Olympic Games, entitled => "Moodido – The Match".
