Bryan Simmons, popularly known as TM88, is a producer signed to Bricksquad Monopoly. He makes unique 808 drum-heavy beats for rappers like Future, Travis Scott, Juicy J, and Lil Uzi Vert.

He was an original member of the production group 808 Mafia, until he split in late 2015 amid controversy surrounding the production of Future’s 56 Nights. He released his unique project Sacii Lyfe in 2015.

He spoke to Fader about his breakup with 808 Mafia:

It’s just a decision that I made. It’s [Southside’s] company. He good, he knows what he’s doing, he’s fine. He’s good at making beats. I’m happy to see both of us succeeding right now and getting money. It wasn’t because of 56 Nights, we decided to part ways. That’s my little brother. It ain’t no hard feelings. I’m killing the game right now, I don’t even be worried about that shit. I got a hundred thousand songs, I’m not worried about no motherfuckin' 56 Nights.

[…] But salute the whole 808 Mafia. It’s still in my soul, it’s on my hand, it ain’t going nowhere. Them my boys. But as far as anybody else in 808 Mafia, I don’t have contact with them. Right now is about that TM88 shit. Keep flaming the industry up. We got a whole bunch of new music out man. 56 Nights was crazy though, man—shout out to Future and Esco.

In 2017, TM produced Lil Uzi Vert’s “XO TOUR Llif3,” his most popular song. In an interview with Genius about this track, he says that “It gives me the feeling of, just the partying feel, it make you feel like a rockstar.”
