Miles Davis - Dual Mr. Anthony Tillmon Williams Process
This tune was recorded on November 11th, 1968. Discographer Peter Losin suggests that this tune may have been co-written by Gil Evans, which is definitely possible. It was shelved but eventually released by Columbia in 1976 on the album Water Babies.
Marcus Miller - Tutu
Recorded on February 11th, 1986. Released on the album Tutu, by Warmer Bros. I didn't bother transcribing all the synth hits at the beginning.
