The album features guest appearances from GLC, Colin Munroe, Ashtrobot, BJ the Chicago Kid, Schoolboy Q, Ab-Soul and vocals from late singer-songwriter Alori Joh. The production was mainly handled by Top Dawg in-house producers from production group Digi+Phonics, along with THC, Tommy Black, Wyldfyer, Terrace Martin and J. Cole. The concept album features lyrical themes delivered by Lamar such as racism and medication tolerance. The album's lead single, "HiiiPoWeR" was released on April 12, 2011.

Section.80 received generally positive reviews from critics. The album debuted with 5,000 copies in the United States, based upon digital downloads within less than a week, debuting at number 113 on the Billboard 200, with minimal mainstream media promotion and coverage – however, some sources suggest the album entered at number 104. Within a two-week period, the album sold in total of 9,000 copies in the United States. As of February 2014, Section.80 has sold 130,000 copies domestically.
