According to Francesca T. Royster, in Rickey Vincent's book "Funk: The Music, The People, and The Rhythm of The One", he analyzes the impact of Labelle but only in limited sections. Royster criticizes Vincent's analysis of the group, stating: "It is a shame, then, that Vincent gives such minimal attention to Labelle's performances in his study. This reflects, unfortunately, a still consistent sexism that shapes the evaluation of funk music. In "Funk", Vincent's analysis of Labelle is brief—sharing a single paragraph with the Pointer Sisters in his three-page sub chapter, 'Funky Women.' He writes that while 'Lady Marmalade' 'blew the lid off of the standards of sexual innuendo and skyrocketed the group's star status,' the band's 'glittery image slipped into the disco undertow and was ultimately wasted as the trio broke up in search of solo status" (Vincent, 1996, 192). Many female artists who are considered to be in the genre of funk, also share songs in the disco, soul, and R&B genres; Labelle falls into this category of women who are split among genres due to a critical view of music theory and the history of sexism in the United States.
