I want to know the answer to the following question:
What musician collaborated with Kanye West for his album Late Registration?
All the background I'm provided with is that "Sean Fennessey of The Village Voice writes that West "absorb[ed] the gifts of his handpicked collaborators, and occasionally elevat[ed] them" on previous studio albums, noting collaborators and elements as Jon Brion for Late Registration, DJ Toomp for Graduation, and Kid Cudi for 808s & Heartbreak.". Is that enough to answer the question?
Answer: yes
