Background and recording. Previously, Brown and Young Thug collaborated on the  official remix of Brown's song "Wrist", contained in OHB and Brown's collaborative mixtape "", on the free-released track "Dat Night", also featuring Trey Songz, and on "High End", a promotional single from Brown's acclaimed eighth studio album "Heartbreak on a Full Moon", also featuring Future. The mixtape was entirely done at Brown's house during the very first stages of COVID-19 pandemic. It was announced by both artists through their Instagram pages on April 29, with its tracklist being revealed a day before its dropping. After its release, Young Thug revealed that, after spending days recording demos  for his verses and elaborating them, he recorded all their official versions in a day. The sound engineer of the mixtape, Patrizio Pigliapoco, talked about the making of the mixtape during an interview with the magazine Revolt, saying that: "It was some days of 30-40 people in Chris' house. Young Thug's crew is massive. It wouldn't be a party, but it would be a kickback while we made the mixtape". The mixtape was announced on April 6, 2020, by Brown on his Instagram account, and on April 28, 2020, the title and release date set for Brown 's 31st birthday were announced. Critical reception. The mixtape received a positive response from the general public. Kenan Draughorne of "HipHopDX" praised the mixtape, saying that on the project, both artists "pair with each other beautifully, creating their best collaborative tape to date", defining it as a "fun-filled amusement park from start to finish, bursting with color from both the acclaimed vocalists and the production beneath them". Draughorne called "Go Crazy" the mixtape's best song. Joe Budden of "Complex"s "Everyday Struggle" called the collaboration project "unexpected" and said that "being a mixtape, the project obviously isn't and  wasn't supposed to be as majestic or inventive as Brown's latest two albums. It's still a well-done tuneful project of 'fun music' that can be easily listened and enjoyed at any time". Commercial performance. "Slime & B" debuted on the charts after being initially available for free on SoundCloud, as well as spending only three days of activity on digital retailers and streaming services. It debuted at number 55 on the US "Billboard" 200. Track listing. Credits adapted from Tidal.
