Answer by taking a quote from the following article:

Sean Michael Leonard Anderson (born March 25, 1988), known professionally as Big Sean, is an American rapper. Sean signed with Kanye West's GOOD Music in 2007, Def Jam Recordings in 2008 and Roc Nation in 2014. After releasing a number of mixtapes, Sean released his debut studio album, Finally Famous, in 2011. He released his second studio album, Hall of Fame, in 2013.

In an interview on Conspiracy Worldwide Radio, Sean discussed the role Kanye West and No I.D. have had in the development of his first studio album's sonic direction as well as the challenges of being inside the studio with West. The album's lead single, "My Last", features vocals from Chris Brown and was produced by No I.D. According to Amazon.com, Big Sean's Finally Famous was delayed by a week, with a tentative release date set for June 28. Big Sean has revealed the cover art for his G.O.O.D. Music debut and explained that the one-week pushback was to be blamed on sample and feature clearance issues. The official track list was revealed on June 7.  Finally Famous, Sean's debut studio album, was released June 28, 2011, and spawned three hit singles; "My Last", "Marvin & Chardonnay" and "Dance (Ass)". The album featured guest appearances from Lupe Fiasco, John Legend, Pharrell, Kanye West, Roscoe Dash, Wiz Khalifa, Chiddy Bang, Rick Ross, Nicki Minaj, Pusha T, and included production from No I.D., The Legendary Traxster, Andrew "Pop" Wansel, Xaphoon Jones and The Neptunes. When the songs "O.T.T.R." and "Flowers" were leaked in July 2011, speculation began of a new mixtape. Sean confirmed in an interview June 28, 2011 that a collaborative mixtape between him and "two other guys in hip-hop that are just killing it right now" will be released "in a couple of weeks". Wiz Khalifa and Curren$y, were the suspected featured rappers on the mixtape. However, Wiz Khalifa later confirmed that there would be no mixtape, claiming that the songs were created, "just for fun".  In September 2011, Big Sean confirmed in an interview with the Daily Tribune that he'll be working on his second album during the I Am Finally Famous Tour and plans to release the album sometime in 2012. On October 19, 2011, Kanye West announced on his Twitter plans for a Spring 2012 GOOD Music album release. On April 6, 2012, "Mercy", the lead single from the GOOD Music compilation album, Cruel Summer, was released. The song, produced by newly signed in-house producer Lifted, features Big Sean along with Kanye West, Pusha T and southern rapper 2 Chainz. Big Sean then announced his fourth mixtape would be titled "Detroit" and would serve as a lead-in to his second studio album. He then began promoting the mixtape, releasing short versions of the songs on his YouTube page. On September 5, 2012, Big Sean released the mixtape Detroit which features guest appearances from fellow rappers J. Cole, Juicy J, King Chip, French Montana, Royce da 5'9", Kendrick Lamar and Tyga.  Big Sean pushed back the release date of his second studio album Hall of Fame, and was eventually released on August 27, 2013. The album has skits to give it a "classic feel", and includes features from multiple artists, including Lil Wayne, Miguel, and Nas. The album's production was primarily handled by No I.D., and Key Wane along with additional production from Hit-Boy, and Da Internz, Mike Dean, Travis Scott, Xaphoon Jones and Young Chop among others. Big Sean also stated in an interview that he was in the studio with fellow Detroit native Eminem.

Hall of Fame had spawned five singles, "Guap", "Switch Up" featuring Common, "Beware" featuring Jhene Aiko and Lil Wayne, "Fire", and "Ashley" featuring Miguel.  A month prior to the release of Hall of Fame, Big Sean told Complex that he had already begun work on his third album due to the inspiration from his new relationship.
