Deliverance (Bubba Sparxxx album): Deliverance is the second album by American rapper Bubba Sparxxx.  It was released on September 16, 2003, by Beat Club and Interscope Records.  It was produced by Timbaland and Organized Noize.  The album debuted at number 10 on the "Billboard" 200 with 64,500 copies sold in the first week released.  Although this album was only moderately successful, selling around 350,000 copies, it is regarded by many critics such as "The Source", "Hip Hop Connection" and more mainstream magazines such as "Q" to be something of a landmark in hip-hop music.  The album's main strength according to critics was that it embraced Sparxxx's grass roots, with production heavily influenced by country music and similar musical styles.  This influence is evident on tracks such as "Comin' Round" which sampled its chorus from a track by the bluegrass group Yonder Mountain String Band, leadout single "Jimmy Mathis" which is led by a catchy harmonica tune from the Area Code 615 track "Stone Fox Chase", and "She Tried" led by a washboard rhythm section and a mellow fiddle sound.
