In Utero is the third and final studio album by the American rock band Nirvana, released on September 13, 1993, by DGC Records.
Soon after recording was completed, rumors circulated in the press that DGC might not release the album in its original state, as the record label felt that the result was not commercially viable. Although Nirvana publicly denied the statements, the group was not fully satisfied with the sound Albini had captured. Albini declined to alter the album further, and ultimately the band hired R.E.M. producer Scott Litt to make minor changes to the album's sound and remix the singles "Heart-Shaped Box" and "All Apologies".
Upon release, In Utero entered the Billboard 200 chart at number one. It has been certified five times platinum by the Recording Industry Association of America, and has sold 15 million copies worldwide.
