Jazz, Classical, and Hip Hop combined into one super group...

Yukimi Nagano
I would definitely need this chick to be my lead singer. Everything that comes out her mouth is so jazzy and emotional and so far has only been used for electronica such as Hird & Little Dragon. This would be a great addition and twist to what I'm used to.

The Cinematic Orchestra
Da hell? Why not. There range of musical diversity is out of this world rediculous. I would have them basically serve as the key musicians.

HiTek
For a little bit of variety for the sound that I'm going for I would definitely have DJ HiTek as the producer to do some of the sampling, scratching, and any synthetic beats that would be required to make the performance/recording hot.

Steve Reich
And of course, Steve Reich would primarily do the arrangements. Shiiiiiddd.....Steve Reich and HiTek together would probably make something sick out of the concept of sound, minimalism, and hip hop all together.
