The Times of London said that on the 39-year-old's "No Promises" album, the former model took poems from literary greats such as W.B. Yeats and put them to music.
Many European music experts are labeling the album as the next big thing in pop culture, The Times said.
While Bruni's musical interpretations of works from Yeats, W.H. Auden, Dorothy Parker and others have garnered high praise, it does not mark the first time such an effort was attempted.
Prior to Bruni's efforts, similar poets had their works placed in songs by singer Joni Mitchell and by composer Benjamin Britten, the report said.
The former model admits the endeavor was not planned, but merely an impulsive reaction to the artistic beauty of the literary works.
"It was not really a concept, more of an impulsive reaction to these poems which leapt off the page at me," Bruni told the newspaper.
