 The music of Crash Bandicoot was a last @-@ minute aspect added to the game before its showing at the Electronic Entertainment Expo . The producer of Universal Interactive proposed that rather than conventional music , an " urban chaotic symphony " would be created by Andy Gavin causing random sound effects ( such as bird vocalizations , vehicle horns , grunts , and flatulence ) to be randomly selected and combined . When this proposal was rejected , David Siller introduced the team to the music production company Mutato Muzika and its founder Mark Mothersbaugh . Following this introduction , Mothersbaugh selected Josh Mancell to compose the music for the game based on his previous work on Johnny Mnemonic : The Interactive Movie . Mothersbaugh advised Mancell throughout the soundtrack 's demo stages , after which all composition duties of Crash Bandicoot and Naughty Dog 's subsequent six titles were delegated to Mancell . Mouse on Mars , A Guy Called Gerald , Aphex Twin and Juan Atkins served as influences on Mancell 's " simple but kind of off @-@ kilter " melodies . Dave Baggett served as the soundtrack 's producer . The sound effects were created by Mike Gollom , Ron Horwitz and Kevin Spears of Universal Sound Studios . The voices in the game were provided by Brendan O 'Brien .
