Input: Question: Has the rapper who Martin collaborated with on the album Kingdom Come won a Grammy?  Passage:Martin's fascination with hip hop was shown in mid-2006 when he collaborated with rapper Jay-Z for the rapper's comeback album Kingdom Come after the two met earlier in the year. Martin put some chords together for a song known as "Beach Chair" and sent them to Jay-Z who enlisted the help of hip-hop producer Dr. Dre to mix it. Coldplay producer Rik Simpson conceived and performed the drum beats. The song was performed on 27 September 2006 by the two during Jay-Z's European tour at Royal Albert Hall. Martin has also worked on a solo collaboration with Kanye West, with whom he shared an impromptu jam session during a 2006 concert at Abbey Road Studios. He performed the chorus of "Homecoming", from Kanye West's album Graduation.
