[3] In 2018, Blurryface became the first album in the digital era to have every track receive at least a gold certification from the Recording Industry Association of America.

"Message Man" was recorded with Tim Anderson at Werewolf Heart in Los Angeles, California.

The album was mixed by Neal Avron, with assistance from Scott Skrzynski, at The Casita in Hollywood, California.

"[10] Joseph wears black paint on his hands and neck during his live shows and music videos for the album, to represent Blurryface, saying: "Very dramatic, I know, but it helps me get into that character.

"[11] Art direction and design was done by Brandon Rike, Mark Eshleman (of Reel Bear Media), and Virgilio Tzaj.

[9] On his blog, Rike mentions the different feel of the artwork compared to that of Vessel and how the red on Blurryface is "the color of passion, violence, and anger", although the band is famous for their content being open to interpretation.

[14] The lead single "Fairly Local" was released on the same day, accompanied by a music video which premiered on the official Fueled by Ramen YouTube channel.

[27] On May 19, 2015, the duo performed at the iHeartRadio Theater LA in Burbank, CA, to celebrate the album's release.

[35] Garrett Kamps of Billboard hailed the album as a "hot mess (in a good way)", but gave it a mixed review, saying that Blurryface "doesn't quite reach the heights of Vessel".

Their critic, Jason Pettigrew, described the album as "wonderful" and hailed the band's mix of genres in their songs, highlighting "Ride", "Polarize", "Message Man", "Tear in My Heart", "We Don't Believe What's on TV", "Goner" and "Lane Boy" in his review.

[43] Jason Pettigrew of Alternative Press wrote that the band combined "hip-hop vistas, tinges of reggae, everyman pop, furious electronic urgency and bellicose sadness into an impossibly cohesive record".

[56] It was the eighth best-selling album of 2016 with over 1.5 million copies sold worldwide that year, according to the International Federation of the Phonographic Industry.

[59] In 2018, the album became the first non-compilation project to have every song certified gold by the Recording Industry Association of America.

Two shows on the tour were recorded at Fox Oakland Theatre and later released as a television special and limited edition vinyl titled Blurryface Live.

Twenty One Pilots began the Emotional Roadshow World Tour in 2016, which also focused mainly on the Blurryface album and character.
