[4] The basic tracks and overdubs were done at Skywalker Studios in California with producer Greg Ladanyi and mixed by Bob Clearmountain.

[4] During the recording of Kingdom of Desire, Toto did a summer tour in Europe, where they played the Montreux Jazz Festival.

In live shows, Toto has often dedicated Kingdom of Desire track "Wings of Time" to Porcaro, who wrote the lyrics, and later, to his brother, Mike, who died from complications of ALS on March 15, 2015.

The final line from the song's chorus can be found on his tombstone at Forest Lawn Memorial Park (Hollywood Hills).

Toto had sold out a number of arena dates in Europe to support Kingdom of Desire prior to the death of Jeff Porcaro.

Though devastated by the loss of a founding member and lifelong friend, the band asked Simon Phillips to play drums on the forthcoming tour.

The first song the band rehearsed with Phillips was "Hydra" and his performance made a strong impression on Paich, Lukather, and Mike Porcaro.
