The album saw a physical release on June 7, 2011, in a deluxe package with liner notes provided by former The New York Times theatre critic Frank Rich, as well as full lyrics and a synopsis of the musical.

Other mixing challenges included "creating enough air and clarity for all the vocalists while still maintaining the vibrancy of [Lopez's] orchestral arrangements", as well as dealing with the score's wide range of musical styles.

[5] Oremus and Lopez were heavily involved in the orchestra recording, whereas Stone and Parker were more invested in the vocal session.

[5] All tracks are written by Trey Parker, Robert Lopez, Matt StoneIn the recording's liner notes, Frank Rich wrote that The Book of Mormon "scrupulously follows the old testament of Broadway circa 1945–1965, A.D., even while fondly spoofing it".

She also likens "I Believe" to "I Have Confidence" from The Sound of Music, citing similarities in their lyrics, and makes a comparison between the Ugandans' version and presentation of Joseph Smith's story in "Joseph Smith American Moses" to "Uncle Tom's Cabin" from The King and I, as well as the recalling and overlap of previous numbers in "Man Up" to Les Misérables's "One Day More".

[8] As the audio was being mixed, the musical's popularity exploded, giving the show a much higher profile than when the album was first recorded.

[5] The cast album was promoted through advertisements running during Parker and Stone's South Park on Comedy Central.

[15] However, after the show's success at the 2011 Tony Awards, The Book of Mormon cast album broke sales records again when it skyrocketed up the Billboard charts back to number 3 on the Billboard 200 on June 15, making it the highest charting Broadway cast album–and first top 10–since 1969, when Hair spent 13 straight weeks at No.

[15] It sold over 61,000 copies, the largest sales week for any cast album since Nielsen SoundScan began tracking data in 1991.

[16] Many news outlets attributed its chart success not only to its physical release on June 7 and publicity from the Tony Awards, but to Amazon MP3's sale pricing of the digital album.

[17] The retailer offered it at just $1.99 for three days during the sales tracking week that ended on Sunday (the night of the Tony broadcast).

[18] Matthew Perpetua of Rolling Stone complimented the recording's witty lyrics and memorable songs and stated the album would leave listeners "desperate to score tickets to see the actual show".
