Reception
Gorilla vs. Bear described it as a "more adventurous version of The Grey Album, but with J Dilla and the Beach Boys standing in for Jay-Z and the Beatles". Pitchfork called it "a surprisingly deft, quasi-mash-up record", while The Guardian wrote that the album "highlighted the beauty of the music by chopping it up into byte-size chunks and putting it back together in fabulous new shapes". In 2013, Fact magazine placed Pet Sounds: In the Key of Dee in its list of the essential instrumental hip hop albums of the last 15 years.
