Task: Question Answering
Input (English): Passage: Following their 2004 reunion, the Pixies felt that recording a new song would "break the ice" between band members after their acrimonious split in 1993. As the band were announcing dates for their reunion world tour, DreamWorks contacted manager Ken Goes to enquire whether they would be interested in recording a song for the title sequence of Shrek 2. The band agreed, and frontman Black Francis and Deal began composing riffs for a song aimed at children. Deal had been experimenting with a chord progression for a while, and since her band The Breeders were then inactive, she decided to donate her new composition to the Pixies.
The Pixies chose Deal's riff, as it was a "poppier, more kid-friendly thing," and Francis agreed to let her sing lead vocals and write the new song; significantly, Francis is relegated to backing vocals on the track. Francis' move was meant to warm the previously cold relations between the two—in the previous two Pixies studio albums, Bossanova (1990) and Trompe le Monde (1991), Francis, the band's principal songwriter, had not let Deal contribute any songs or sing lead vocals. This became one of the reasons for the Pixies' 1993 split. However, the two appeared at the time to have resolved their differences: Francis praised "Bam Thwok," as "a really good song." despite joking in interviews about how he planned to remove as many of her compositions as possible from a hypothetical new album. However, Deal eventually left the band in June 2013, before the release of the band's next album, Indie Cindy. 
Question: What is the name of the person that donated her new compostion to the Pixies?
Output (English): Deal.
