In late 2005 Ghostface Killa and MF DOOM were both recording over tracks from J Dilla's instrumental opus, Donuts, which saw release the following February. Some of these were released on Ghostface's Fishscale in 2006, while others, including a Dilla-Doom project, were postponed indefinitely after J Dilla's passing. Two of these tracks, “Sniperlite” and “Murder Goons,” will be released digitally, exclusively through Stones Throw's webstore, due to launch in late June.
