Toto

After the release of Toto IV, Mike Porcaro (brother to Jeff and Steve), joined the group on bass, replacing Hungate. In 1984, Bobby Kimball left the group after being arrested for selling cocaine and was replaced by Dennis Frederiksen aka Fergie Frederiksen, who was replaced not long after by Joseph Williams.

Steve Porcaro left the band in 1988, however, he still contributes as a sideman.

In 1990, Jean-Michel Byron replaced Williams for the new recordings on Past to Present 1977-1990, then left with Lukather becoming the group's lead singer.

On August 5, 1992, Jeff Porcaro died of a heart attack, days after completing work on Kingdom of Desire. The group considered disbanding, before adding British drummer Simon Phillips for the subsequent tour. In the years since Porcaro's death, Lukather has seemingly succeeded Paich as the band's de facto leader.

In 1999, Bobby Kimball returned to the lineup after a 15-year absence.

Greg Phillinganes joined the lineup in 2004 to fill in for David Paich during a tour, then officially joined Toto in 2005.

After a period of rumours and some allusions, on June 5th, 2008 Steve Lukather made an official announcement on his website stevelukather.net, stating: "The fact is yes I have left Toto. There is no more Toto." Lukather further stated that after 31 years of recording, producing and playing with Toto without even missing one single gig, he couldn't do it anymore: "I just can't do it anymore and at 50 years old I wanted to start over and give it one last try on my own." With Lukather being the only original member left in the band (Bobby Kimball was also an original member, but was out of the band from 1984-1998) there was no other option than to call it quits. As the main motivation for his decision, Lukather said: "When Dave retired that was REAL hard for me 'cause we started the band together. Hell, it's 35 years if you count High School where the core all met. When Mike fell ill and had to leave that was it for me. If there isn't Paich or at least one Porcaro how can we even call it Toto?" Luke also stated: "Honestly, I have just had enough. This is NOT a break. It is over. I really can't go out and play Hold The Line with a straight face anymore." The break-up of Toto after 31 years received mixed reactions from the fans, but in general the decision was understood and many agreed with Lukather's reasons to quit the band.

On April 5th, 2008, Toto played what would be their last show ever, in Seoul, Korea, as a part of their Falling In Between Live tour. This left lots of fans without a real farewell tour.

On February 26th, 2010, Steve Lukather announced on his Twitter-account that Toto are reforming for a brief tour in Europe in the summer of 2010 to honor bass player Mike Porcaro, who's suffering from ALS syndrome. Line-up will include David Paich, Steve Lukather, Steve Porcaro, Simon Phillips, Joseph Williams and Nathan East.

Toto released their fourteenth studio album and their first in nine years titled Toto XIV on March 20 (Europe), March 23 (UK and Oceania), and March 24, 2015 (North America). To promote the newly finished project, the band started a world tour running with an extensive European headline arena tour including appearances at key festivals, along with a North American tour to follow in the summer of 2015 and Asia later that year.

On March 15, 2015, former bassist Mike Porcaro died, due to complications from his battle with ALS, in his sleep at his home in Los Angeles.

On 6 April 2015, Toto announced that they would embark on 7 August 2015 in Mashantucket, Connecticut with veteran progressive band Yes on a joint summer tour of North America due to end on 12 September 2015 in Coquitlam, British Columbia. Shannon Forrest has continued to perform as the band's drummer.

On 29 September 2015, Toto announced the first leg of their 2016 Tour in support of Toto XIV consisting of European and Japanese dates. Leland Sklar, who joined them on their 2007 and 2008 tours, replaced founding member Hungate. Sklar left Toto in early 2017 and was replaced by Shem von Schroeck.

Toto will release their anniversary album "40 Trips Around The Sun" on February 9, 2018. Then, they'll embark on their world tour promoting their album and celebrating 40 years of music.
