Terry Sanchez Wallace Jr., known professionally as Tee Grizzley, is an American rapper. He first began posting music online following a two year prison sentence, self-releasing his 2017 song "First Day Out". It quickly gained viral status—earning two million views on YouTube in under three weeks—due to a social media challenge enacted by American basketball player LeBron James, after which the song peaked within the top 50 of the Billboard Hot 100 and led him to sign with 300 Entertainment. Its release preceded his debut mixtape My Moment (2017), and was followed by the single "From the D to the A", which received double platinum certification by the Recording Industry Association of America (RIAA). His collaborative mixtape with Lil Durk, Bloodas (2018), was followed by his debut studio album, Activated (2018).
