Kanye’s second album Late Registration displayed some changes in his production style, incorporating the help of producer and film score composer Jon Brion.  His interest in Brion came mostly from his work on the film Eternal Sunshine of The Spotless Mind, and on Fiona Apple’s second album, When The Pawn… For many of the tracks on Late Registration, Kanye combined his own style with the advanced instrumentation of Brion, creating a more multi-layered sound.  Whatever the strategy was, it worked, giving the album mega-success in a very rough quarter for sales.  With that said, there was one track on the album not produced by Kanye; “Touch The Sky,†a Just Blaze production.
For this record, Just Blaze used a slowed down sample of Curtis Mayfield’s “Move On Up,†off of Mayfield’s debut solo album, Curtis. The main section he puts to use is the opening four bars, which he layers with very busy drums; kicks, claps, snares, and frequent cymbal crashes.  Certain parts of the beat you can also hear chops of the high pitch strings from 0:15 and 0:19.  In the verses, he opens the beat up for the vocals, using stabs of the sample every 2 bars.  Glad Yeezy allowed an outside producer on the album, because this record definitely contributed to it’s overall sound.
Gotta testify, come up in the spot looking extra fly.  Before the day I die, I’ma touch the sky.
