GTR was a short-lived rock band founded in 1985 by former Yes and Asia guitarist Steve Howe and former Genesis guitarist Steve Hackett. In comparison to the two leaders' earlier work within progressive rock, GTR appealed to album-oriented rock radio stations. The band was short-lived, lasting for two years and one album. Hackett has subsequently been strongly critical of the project, though not necessarily of the other musicians involved in it.
The band's name came from an abbreviation of "guitar" as used for track labelling in multi-track recording studios.
