'Worth It' was for Danny Brown, 'Leave With You' was for Lucki, 'Kali Yuga' was for Ghostmane, and 'Stem / Long Stem Remix' and 'Elastic Heart Remix' were remixes done for DJ Shadow and Sia. 'Surf,' 'Norf Norf,' and 'Summertime' were all originally for Vince Staples.

Mixtape tracks 'Uncle' and 'Talk It' were originally produced for A$AP Ferg. The last edition of his instrumental mixtape series, Instrumental Tape 3, came out in 2013. He first announced the mixtape on Saturday, when he also shared the gauzy, spaced-out track 'Wavey.' 32 Levels, his debut album, was released last year. Instrumentals 4 features two previously unreleased tracks-'Say Your Prayers' and 'Wavey'-as well as a host of beats and remixes he's done over the last few years. The streaming version of the mixtape includes a new song Sandman, produced by Kelvin Krash and Rocky’s.
