The underlying themes of both albums deal with womanhood and Amos's own miscarriages and marriage. Reviews for "From the Choirgirl Hotel" were mostly favorable and praised Amos's continued artistic originality. Debut sales for "From the Choirgirl Hotel" are Amos's best to date, selling 153,000 copies in its first week. "To Venus and Back", a two-disc release of original studio material and live material recorded from the previous world tour, received mostly positive reviews and included the first major-label single available for sale as a digital download.
