Task: Question Answering
Input (English): Passage: American singer Prudencesa Renfro, professionally known as Pru, was signed through Warner/Chappell Music Publishing by Capitol Records' executive Roy Lott, who said that he was "drawn to" her songwriting and voice. 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. On her official website, the singer identified her style as connected with the soul. Though AllMusic gives the singer songwriting credit on twelve of the tracks, Pru is only credited for co-writing "Aaroma" on the album's liner notes. The record was completed at Studio 57 and Weight Room in New York City, with mixing handled by Mike Shipley and Tony Maserati. Following release of the album, Pru spoke highly of her experiences with the producers and felt that they "la[id] a good bed around the lyrics and the melodies". 
Question: What is the last of the person who worked closely with a singer to match her songwriting to the most appropriate sound?
