 Early in the game 's development , the music team were shown an early build of the game before working on the score . Their work was mostly complete later in the game 's development but they continued composing until the final build of the game had to be submitted for manufacturing . Edgar Froese , Tangerine Dream 's founding member , was not initially interested in being involved in producing music for the game . After he was flown to the studio and shown Grand Theft Auto V , he was impressed by the game 's scale and cinematic nature , and changed his mind . Froese 's first eight months of work on the score produced 62 hours of music . He recorded with Tangerine Dream in Austria but further work was conducted at Jackson 's studio in the United States , which The Alchemist and Oh No also used . Jackson learnt that the composers would be building on each other 's work and expressed concern that the finished product could be disjointed . His initially provided score for Trevor 's missions , citing The Mars Volta and Queens of the Stone Age as stylistic influences . After sending his work to the other members of the team , Jackson was impressed by Froese 's contributions to his work . " Edgar evolved the music , made it into a whole other thing " , he said . Froese had taken Jackson 's hip hop @-@ influenced work and interpolated it with a funk sound . Froese and Jackson also sent their work between The Alchemist and Oh No , who heavily sampled their work . The Alchemist opined , " We were sampling , taking a piece form here , a piece from there ... We pitched stuff up , chopped it , tweaked it . Then we chose the tracks that worked and everyone came in and layered on that " . DJ Shadow then mixed the team 's creations together and matched it to the gameplay .
