Ambrosia currently tours internationally and has worked in the past and present with Alan Parsons, Bruce Hornsby, Bill Champlin, Michael McDonald, and Peter Beckett among other notable artists.

[1] The group was founded as a quartet with guitarist/vocalist David Pack, bassist/vocalist Joe Puerta, keyboardist Christopher North and drummer Burleigh Drummond.

The founding constituents of Ambrosia were reared in Southern California's South Bay, later adopting San Pedro as their hometown.

Ambrosia fused symphonic art rock with a slickly produced pop sound,[6] resulting in a "melodic prog" style.

Gordon Parry, the head engineer in charge at the Bowl, was so impressed with the group that he invited them back to attend performances by the Los Angeles Philharmonic.

The album yielded the title song and the single "Can't Let a Woman", which both became FM favorites, both featuring lush orchestration and vocal arrangements.

In 1976 the group recorded the Beatles song "Magical Mystery Tour", for the transitory musical documentary, All This and World War II (November 1976).

Extensive touring with Fleetwood Mac, Heart, and the Doobie Brothers, in addition to major headlining shows, cemented Ambrosia's reputation as a live act.

[9] For the 1978 touring band, North returned and the group added a second keyboardist, David C. Lewis, as well as an additional singer, Royce Jones, who joined in late 1978.

For the Japanese leg of the tour, the group was joined by their longtime friend Cliff Woolley (formerly of The Association, who had also guested on Life Beyond L.A.) on guitar, harmonica, and backup vocals.

The following year they placed another track, "Poor Rich Boy" (written by Burt Bacharach), on the soundtrack of the film, Arthur.

The same year, Ambrosia released their fifth and final studio album, Road Island (May 1982[12]), their first effort without the assistance of Freddie Piro's production company.

Jackson was in place on guitar for their 2001 shows, except for one gig at Stone Mountain Park in Georgia on August 25 where Steve Farris (from Mr. Mister) subbed for him.

Ollestad remained on call to sub for various band members and came back to play with Ambrosia's spring 2009 tour in place of Lewis and Shem.

In 2012, Burleigh Drummond's wife Mary Harris, after filling in on a show or two since 2000, became a permanent band member on keyboards and vocals.

Ambrosia's six-person lineup was then stable for a while and the group continued to tour, sometimes combining their talents with other artists including Bill Champlin, Peter Beckett, Michael McDonald, Edgar Winter, Dave Mason, Gary Wright, Al Stewart and others.

Ambrosia continues to feature a majority of the band's founding members, with Puerta, Drummond and North onstage, as they have been for the past thirty plus years.

Former member Shem von Schroeck returned in the fall of 2022, this time on drums, to sub for Drummond, who was recovering from back surgery.

David Pack released two 2005 solo projects: Unborn, a compilation of older unreleased material, and the more up-to-date The Secret of Movin' On featuring collaborations with Timothy B. Schmit of Eagles fame, former Journey vocalist Steve Perry, Heart vocalist Ann Wilson and America co-founder Dewey Bunnell, amongst others.
