Like most open challenges, use these samples.
The song: The Silver Mt Zion - The Triumph Of Our Tired Eyes
The break: David Axelrod - The Warning Part 1
The rap: Part 2 & Juice Aleem - Nanotech Pilots (A Capella)
Use any other sounds, instruments, samplers, DAWs with these. Make whatever you want with them. Just make sure you use each of the supplied samples.
Just like the last open challenge: PM me the link to your track, don't make it public. After the due date I'll post each of the submissions anonymously for voting. These fellas know the score.
The comp runs until midday (UTC) 20th of May (time zone list is here).
Good luck!
