"Today I got one of the highest honors a person can receive, the key to the City Of Detroit," Big Sean wrote on Instagram. "The mayor said he's given it to 3 people... Stevie Wonder, Berry Gordy, and Me. I'm the youngest person to receive this in the history of the city!"
Earlier this month, Big Sean launched Mogul Prep, a series of small workshops aimed at teaching middle and high school students from low-income backgrounds the inner workings of the business side of the music industry.
The first Mogul Prep took place Saturday afternoon in Detroit prior to Big Sean's concert at the city's Fox Theatre, with similar seminars set for Baltimore, Miami and Atlanta.
"[The mayor] honored me and my foundation for motivating the city through my music [and] messaging and starting an actual curriculum called 'Mogul Prep' that teaches kids all the behind the scenes jobs available in the music industry and taught to them at a high school level," the rapper added. "This will be applied to Detroit Public Schools come this fall and some schools in Baltimore and more."
In addition to helping out the Motor City, the I Decided rapper also donated $100,000 to the city of Flint for the victims of their water-poisoning crisis and constructed a recording studio at his former high school.
