High and Mighty was the last Uriah Heep album to feature bassist John Wetton, and vocalist and founding member David Byron who was fired later that year due to his troubles with alcohol and differences with band priorities.

The album was remastered and reissued by Castle Communications in 1997 with two bonus tracks, and again in 2004 in an expanded deluxe edition.

"Several of the songs find the band flirting with pop elements in a way that doesn't complement their hard rocking style", said Donald A. Guarisco in his retrospective AllMusic review.

He added that High and Mighty "shows flashes of the group's old firepower, but is ultimately sunk by a combination of unfocused experimentation and uneven songwriting".

[4] Martin Popoff called the album "effeminate, illogical, overblown, grasping for straws", citing only the song "One Way or Another" as "promising" and the rest a squandering of "the band's flickering talents".
