GTR and GT-R can refer to:
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.
GTR is the 1986 self-titled debut album and sole official studio release from the short-lived supergroup GTR. The album peaked at No. 11 on the Billboard 200 chart, and the single "When the Heart Rules the Mind" reached No. 14 on the Billboard Hot 100 singles chart. Another single, "The Hunter", peaked at No. 85. The instrumental piece by Steve Howe, "Sketches in the Sun", resurfaced on his solo album Motif Volume 1 and again on his Anthology album. Steve Hackett's "Hackett to Bits" was a simplified version of the title track from his Please Don't Touch album. (It had no connection with the similarly titled "Hackett to Pieces" from Highly Strung.)
The group, founded by ex- Genesis guitarist Steve Hackett and then ex- Yes and ex- Asia guitarist Steve Howe, disbanded in 1987. Geoff Downes, another former Yes member, produced the album.
The band's name, anecdotally, comes from the marking on the studio mixing console that indicates the 'guitar' volume control.
The album was reissued in 2001 in a remastered CD edition. The album was out of print, with the exception of a Japanese mini-LP CD released in 2006, until a deluxe 2-CD version was released in 2015.
