From the NY Times:
The news everybody has been waiting to hear about the Pixies reunion has been confirmed: They have indeed recorded new music. The band's first new song in 13 years, "Bam Thwok," is available for download on Apple's iTunes Music Store. The song, recorded in March, was written by Kim Deal, the bassist, who said in a statement yesterday that her lyrics were inspired by a young person's notebook she found on the street. "This kid had written a short story, a paragraph really, about a party that took place in another universe, about people and monsters that were partying together," she said. "It's a song about loving everyone, showing good will to everyone." The chorus goes: "Love. Bang. Crash. Wakka, wakka, Bam Thwok."
Kim never was much for lyrics, was she?
