GTR was a supergroup formed by Steve Hackett and Steve Howe, guitarists for Genesis and Yes, respectively.
The band was on the cutting edge of using MIDI-equipped guitars to create a modern, synthesizer sound without keyboards.
Their album hit number 11 on the charts, and its first single, “When the Heart Rules the Mind” got to number 14 on the Billboard Hot 200, and remained on the chart for several months.
