Porcaro's career as a touring musician began at the age of 17, playing with
Gary Wright on the 1975–76 tour in support of his album,
The Dream Weaver. The following year, he joined
Boz Scaggs'
Silk Degrees tour, along with his brothers Jeff and Mike, future
Toto bandmates
David Paich and
David Hungate, and later
Steve Lukather and
Lenny Castro.
Toto In 1978, Columbia Records released
Toto's self-titled debut. The band would go on to become one of the best-selling bands of the era and achieve successful singles such as "
Africa", "
Rosanna", and "
Hold the Line". Their album
Toto IV has been certified quadruple platinum in the United States. Porcaro wrote or co-wrote one track on each of Toto's first six albums except for
Isolation. The title of the song "
Rosanna" was inspired by Porcaro's then girlfriend, actress
Rosanna Arquette. Though she did not directly inspire the song's lyrics, her name fit the song perfectly as described by the song's writer,
David Paich, on HBO's
Music Box: Yacht Rock: A Dockumentary. In 1984, Toto composed music for
David Lynch's
Dune. In 1987, Porcaro left the band to focus on songwriting and scoring, although he accompanied them on their 1988
The Seventh One tour and continued working with them in various capacities, assisting with keyboards,
synthesizers, and programming on all the band's albums following his departure.
Other work After his departure from Toto, Porcaro composed music and arranged orchestration for such film/TV as
Quentin Tarantino and
Robert Rodriguez's
From Dusk Till Dawn 2: Texas Blood Money,
Eddie Murphy's
Metro, and
Jackie Chan's
The Medallion. He also developed music for the television series
Justified. He wrote the song "
Human Nature", which appeared on
Michael Jackson Thriller album. The demo of "Human Nature" was sent to
Quincy Jones via a cassette tape, which also included a few songs written by Paich. Jones was fielding material from various composers to consider for
Thriller and elected to present "Human Nature" to Jackson. Porcaro said that he did not intend for Jones to hear his demo of "Human Nature" and explained that he placed the track on the back of the cassette as he lacked any other tapes to store the song. From 1982 to 2009, he composed or co-wrote many other songs for Jackson, including "
Chicago 1945", "Dream Away", and "
For All Time". In 2024, Porcaro sold the rights to all his music to the
estate of Michael Jackson and publisher
Primary Wave. In 2010, Porcaro returned to play with Toto at live performances when they reformed for a tour in Europe to support
Mike Porcaro, who was suffering from
ALS. He performed on the band's 2015 studio album
Toto XIV, co-writing and singing lead on "The Little Things" and co-writing/singing lead on the Japan-only bonus cut, "Bend". When the band dissolved in 2019 and regrouped in 2020, Porcaro did not return. In 2018, indie rock band
Weezer covered Toto's "Africa", which was prompted by a fan campaign. Porcaro joined the band onstage for a performance on
Jimmy Kimmel Live!. In 2024, Porcaro appeared on
HBO Original documentary
