Let there be no doubt Bun B has hustle blood running through his veins. Since the untimely death of his partner in crime Pimp C, Houston’s torchbearer has continued to grind, releasing three solo joints and showing up as a sidekick on more teams than Shaq. As it usually happens, the hard work has paid off. With the third installment of his Trill series: Bun B and friends have released a smooth collection of southern-fried gangster rap to cap off a great summer of Hip-Hop.

Trill O.G. features few surprises in the way of topic or song structure, relying on immaculate production, perfect polish and unflappable consistency. Bun remains in his mid-90s comfort zone throughout, calling in a few favors to give the album some modern zest. Call it the Senior Citizen Blueprint. The first of two Drake collaborations “Put it Down,” starts with a fierce verse from Bun before descending into Drake’s melodic chorus. The benefits to both are obvious, as Bun modernizes his sounds while providing rap’s favorite Canadian with some badly needed street cred. More natural partnerships form the foundation of the album. Bun, Gucci Mane and Yo Gotti take turns boasting on bank accounts on “Countin’ Money” over a hefty beat. Better yet is the Jeezy collaboration “Just Like That,” a monstrous duet between cocaine rap’s Chosen Son and forefather. The combination of Drumma Boy’s cinematic synths, Jeezy’s brillo chorus and thuggish rhymes make for a car-banging classic.

Killer production drove the rise of the South and this album carries on that tradition. Grimy bumpers such as “I Get Down for Mine,” are the norm, balanced by smoked out keyboard grooves such as the intoxicating “Ridin’ Slow.” The best audio comes from fellow Texan DJ Premier on the powerful “Let Em’ Know.” Though unsurprisingly, it has a classic urban jazz feel associated with the NYC. Bun comfortably rips the string rhythms to shreds, proving his style transcends outside of Dixie: “Bun is on the mic/Premier’s on the track/The South is in the House/No One Can Fuck With That/I take shots and don’t miss/First on your baby momma’s bucket list.”

While decades in the game have given Bun perspective that life is more than pimps, hoez and bankrolls, on Trill O.G. he seems content to stay within that lane. There’s occasional nuggets of wisdom. The grind of touring forms the subject of the upbeat “Lights, Camera, Action.” and Bun gets down right sentimental on the poignant “All a Dream.” But this album’s not about reinvention—tracks titles, beats and lyrics like “Snow Money,” and “I Get Down 4 Mine” could come from any UGK album.

Of course, both those aforementioned tracks are straight bangers. Still, it’s the lack of innovation that keeps this album from breaking that artistic glass ceiling. Showcase track “Trillionare” also exposes chinks in the armor of Bun’s rhyme. Individual lines sacrifice wit to ensure Bun stays on flow, resulting in occasionally corny lyrics such as “we trying to take this to the mountain top, Appalachians’ or “Go ask the white boy/he say he’s totally tubular.” Compound this with a few ill-advised guest choices (Note to Bun: T-Pain’s career is deader than Pimp C and Tupac’s,) and Trill O.G. is anything but flawless even if it never dips too low.

Focusing on such flaws misses the point of UGK and Bun B’s music and legacy. As a pioneer of the sound and lifestyle of Southern Hip-Hop, Trill O.G. is a fitting reminder of the mass appeal this brand of music reflects when executed properly. It may not be the best album of this summer, but it’s surely the one you’d want to ride dirty to.
