Jack Ponti, of Cazzy Dog Management, had helped Pru produce a demo tape to secure the record deal. Lott had noted Pru's potential as an artist through her lyrics. He worked closely with her to match her songwriting to the most appropriate sound, serving as the executive producer for her debut studio album Pru.Prior to securing a record deal, Pru had found inspiration for her music in artists such as Cassandra Wilson and Dianne Reeves. She wrote song lyrics and poetry while attending high school and then Texas Southern University, coupling her lyrics with the music of other artists such as Michael Jackson, Rachelle Ferrell, Sade, Naughty by Nature, the Isley Brothers, and Miles Davis. While discussing her approach to songwriting, Pru elaborated: "From a word, I can get a whole picture, a visual. The song becomes a poem, almost like a thesis." She considered her music as a form of poetry, citing the album track "Hazy Shades" as an example of a poem turned into a song.Pru stated that she wanted her songs to bring variety to contemporary R&B, and described the material as the opposite of the formulaic music typically found on radio.
