The style is distinguished primarily by melodic sing-song rapping over rhythmic bouncy beats laced with strictly-incorporated “bluesy” (or “country”) guitar-tinged riffs and chords.
[4] Although St. Louis Bounce borrows pounding basslines from Southern rap styles, it is usually distinguished by fairly strict bluesy (or "country") guitar riffs and chords on top of (or around) infectious bassy or percussive beats, which are sometimes accompanied by whimsical lyrics.
Artists associated with the sound include Basement Beats (Jason "Jay-E" Epperson, Waiel "Wally Beamin" Yaghnam, Lavelle "City Spud" Webb and Jayson "Koko" Bridges), The Trak Starz (Alonzo "Zo" Lee Jr. & Shamar “Sham” Daugherty), The Trackboyz (Mark Williams and Joe Kent) production teams; and Steve “Blast” Wills, who claims to be the sound's originator.
[7] The sound was heard prominently on the albums Jackpot, Powerballin', and Hoodstar, performed and released by St. Louis-based rapper Chingy in the early 2000s.
The Trackboyz's version of St. Louis Bounce used "unique beats and production that feature breathy gasps, visceral grunts, heel-pounding stomps, and wild clangs".
