Produced solely by Tyler himself, the album features guest appearances from Playboi Carti, Lil Uzi Vert, Solange, Kanye West, and Jerrod Carmichael.

In its first week of release, Igor debuted at number one on the US Billboard 200, moving 165,000 album-equivalent units, becoming Tyler, the Creator's first US number-one album.

[1] In an interview with Fantastic Man for their Autumn and Winter 2018 issue, Tyler was asked if he had ever been in love, to which he replied: "I don't want to talk about that.

[7] Rolling Stone writer Danny Schwartz described Igor as a "rich and messy mélange of R&B, funk and rap".

[11] American comedian Jerrod Carmichael serves as the album's narrator as it progresses, speaking short lines to make sense of Tyler's and the title character Igor's state of mind.

The arrival of Igor serves as a reset for the strong romantic emotions Tyler was entangled in during the album's first half.

[16][17] Tyler declares his love for a former partner and regrets dating someone else in "New Magic Wand";[18][19] he further details his relationship in "A Boy is a Gun", where he describes his intimate life.

[22] On June 3, 2019, Tyler announced his forthcoming tour for the album, which was supported by Jaden Smith, Blood Orange, and GoldLink.

Roisin O'Connor of The Independent called the album Tyler's "best work to date", emphasizing its unconventional structure and intricate production.

[20] Similarly, Andy Kellman of AllMusic commended the album for its emotional depth, comparing it to a classic soul LP for its expression of "pain, vulnerability, and compulsion",[30] while Danny Schwartz of Rolling Stone appreciated the vulnerability Tyler displayed, explaining that he reveals himself as a "shape-shifting artist who is still growing".

[10] Other critics highlighted IGOR's evolution in Tyler's sound, noting its blend of pop, soul, and hip-hop influences.

Danial Spielberger of HipHopDX commented on Tyler's more polished style, which, despite moving away from his rapper persona, creates a "hazy pop" album that invites risk-taking.

[16] Nick Roseblade from Clash noticed this shift in tone as well, describing how Tyler's previous aggressive style has softened into "slower beats and irresistible soul hooks".
